FAQs of Hose Joint Gas Ball Valve

1. What is the difference between a gas ball valve and a water ball valve?

The core difference between a gas ball valve and a water ball valve is reflected in the medium adaptation design, safety requirements, and material focus.

A gas ball valve is made for gases like natural gas or LPG, which can burn or explode. Because of this, it needs very strong sealing to stop leaks. It often uses special seals like PTFE and has a safer, leak-proof design. The valve body is usually brass or cast iron, which works well with gas and heat. Many gas valves also need special safety certificates. A water ball valve is made for water. Its seal is designed to deal with scale and dirt in water. The material can be plastic or brass, and it must be safe for drinking water, such as being lead-free. It does not need an explosion-proof design.

In addition, the gas ball valve flow channel design pays more attention to gas flow smoothness to reduce resistance, water ball valve may be designed for scale, impurities more easily clean structure, the two can not be mixed, misuse will cause safety risks (such as gas ball valve for water pipe may affect the water quality due to material dissolution, water ball valve for gas is easy to cause leakage due to insufficient sealing).

2. Is the Hose Joint Gas Ball Valve a “full bore” design?

The core feature of the full-diameter model is that the circulation aperture of the ball core in the valve body is essentially consistent with the inner diameter of the valve body inlet and outlet, as well as the connected gas pipeline. The full-diameter design has a significant effect on the improvement of gas circulation efficiency.

Because of this design, gas meets less resistance when it goes through the valve. Pressure loss is smaller, and the gas can flow more smoothly and steadily. This is very useful in places that need a stable gas flow, such as home gas stoves or small commercial gas equipment. At the same time, less gas is left inside the valve after use. This helps lower the risk of corrosion and makes cleaning and purging easier during later maintenance, which helps keep good performance for a long time.

Non-full-diameter valves have a smaller hole inside, so gas flow resistance is a bit higher. However, they cost less and are good enough for simple gas lines where the flow demand is not high.

3. How to select the diameter of the Hose Joint Gas Ball Valve?

First, confirm the pipe diameter and rated flow corresponding to the DN specification of the valve body to avoid insufficient flow due to a too small joint diameter. Secondly, select the joint according to the actual inner diameter of the gas hose. If the hose is standard,(For example, the corresponding inner diameter of 4-point hose is φ12mm), directly match the joint of DN15 valve body with the exact specification; finally, in combination with the use scenario, verify the flow capacity matching between the joint and the valve body through the flow calculation formula, and refer to the hose specification or sample provided by the customer to ensure that the joint insertion depth matches the hose wall thickness to avoid falling off or sealing failure.

Small body (such as DN08/DN10) usually matched with φ8mm/φ10mm inner diameter hose joint, DN15 (4 points) valve body multi-matching φ12mm/φ15mm joint, DN20 (6 points) valve body corresponding to φ16mm/φ20mm joint, large size DN25 (1 inch) valve body matching φ22mm/φ25mm joint, some memorable scenes will use “reducing joint” to achieve reducing adaptation (For example, DN15 valve body is equipped with φ10mm joint), but it is necessary to ensure that the flow resistance is within the allowable range.

4. What is the MOQ for Hose Joint Gas Ball Valve?

The MOQ for a Hose Joint Gas Ball Valve depends on the valve size and how it will be used. For custom or special models, such as large sizes like DN40 or DN50, special thread types, or industrial valves with explosion-proof design, the usual MOQ is about 500 pieces.

For customers who work with us for a long time, or for large orders, the MOQ can be more flexible. For example, if the total order is more than 1,000 pieces, some special or non-standard models can be made with a lower MOQ. The final quantity is discussed and agreed on by both sides when the order is confirmed.

5. Can I return a Hose Joint Gas Ball Valve with a hose connector if it was selected incorrectly?

If a Hose Joint Gas Ball Valve has problems because the customer chose the wrong model, the return or exchange will be handled based on the product condition and the cooperation situation. Our main rule is: if there is no quality problem, both sides solve it by discussion and protect each other’s interests.

If the product is not opened, not used, and the package and labels are complete, the customer can apply for a return or exchange within the agreed-upon time after delivery (usually 10–15 days). In this case, return or exchange is possible, but the customer needs to pay the two-way shipping cost and related fees, such as customs declaration and clearance. The product must also be in good condition and still suitable for resale.

If the product has been opened, installed, or used, or shows wear or damaged markings, returns are usually not accepted. Gas valves are safety products, and used items may affect safe use. However, we can offer other support, such as a discounted replacement, changing to another size, or help with resale solutions.

To reduce wrong selection, we provide clear selection guides before ordering, helping customers check pipe size, pressure, and gas type. For long-term partners or large orders, we can also offer sample testing. Return and exchange rules can be clearly written in the contract, so both sides know their rights and duties.

6. What is the advantage of Plumberstar’s hose joint gas ball valve?

The main advantages of Plumberstar hose fitting gas ball valves are strong materials, high safety, and wide usability.

First, the material is strong and durable. The valve body is made of one-piece casting and forging, making it less prone to breaking. Inside, it uses PTFE sealing material, which can resist gas corrosion and wear. Compared with common cast iron or mixed copper valves, this design lasts much longer, with a service life more than 30% longer than the industry average.

Second, the safety level is very high. The valve meets both CE and UL standards. It has an explosion-proof ball design and a double sealing structure to prevent gas leakage. Each valve is tested according to EN 12266, and the leakage level is almost zero. It can be safely used for natural gas, liquefied gas, and other gas types without extra selection.

Third, it is easy to match and install. The valve supports PT, NPT, and G threads, with sizes from DN08 to DN50. Special hose sizes can also be customized. The common “external thread + hose nipple” design has very accurate size control (±0.1 mm), fits many kinds of gas hoses, and can be installed easily without special tools.

7. How many times can the hose joint gas ball valve be opened and closed?

The opening and closing life of a hose joint gas ball valve mainly depends on the seal type and the material process.

Valves with soft seals, such as PTFE seals, can normally work more than 100,000 open-and-close cycles in a stable way. For metal hard seal valves, the sealing surface is specially hardened (for example, with tungsten carbide coating). These models usually reach over 50,000 cycles, and some specially customized, high wear-resistant types can also exceed 100,000 cycles.

This performance is much higher than the basic industry requirement of 10,000 cycles for gas stove valves. It is also better than the common market level of 5,000–80,000 cycles for ordinary gas ball valves.

The main reason for this long service life is the high-purity brass one-piece forged valve body, combined with nitriding treatment on the valve stem and a precise sealing structure design. These features greatly reduce friction and wear during each opening and closing action.

Even under normal gas working temperatures from –20 °C to 90 °C, after 100,000 cycles, the wear on the sealing surface can still be controlled within 0.1 mm.

8. How do you handle delays caused by Hose Joint Gas Ball Valve raw material shortages?

We have a clear and practical plan to deal with delivery delays caused by raw material shortages for hose joint gas ball valves.

First, we keep a safe stock of key materials like brass and stainless steel. This stock can support about 30 days of normal production. At the same time, we work long-term with more than three approved material suppliers. If one supplier cannot deliver, we can quickly switch to another to keep production moving.

Second, once we see a risk of material shortage, we will inform customers as early as possible. We explain why the shortage happens, how long it may last, and what we can do next. Possible solutions include using alternative materials with the same performance or adjusting production priority to protect important orders.

Third, we will adjust production plans to reduce delays. This includes improving workflow, rearranging production lines, and using factory capacity more efficiently, so the waiting time can be kept as short as possible.

Finally, if an order is still delayed, we will discuss compensation solutions with the customer. This may include a price discount or a longer warranty period, helping to reduce the customer’s loss and keep the cooperation stable.
