FAQs of Gas Ball Valve

1. Can you provide a gas ball valve with an antistatic and fireproof structure?

Plumberstar specializes in gas ball valves with antistatic and fireproof construction. CW510L lead-free brass or 304/316 stainless steel (customizable as required) is selected for the valve body, while forged steel or stainless steel is used for the ball body, offering excellent hardened, corrosion-resistant, and high-temperature-resistant properties. And natural gas, liquefied petroleum gas, artificial gas, and other gas media are suitable. CE, DVGW, ATEX explosion-proof certification, and other international authoritative certification standards.

2. What are the gas ball valve payment methods supported by Plumberstar?

Plumberstar sells gas ball valves to B2B customers and offers different payment methods to match order size and corporate needs. All payment options are safe and meet trade rules.

T/T (Telegraphic Transfer) is the most common payment method. In most cases, customers pay 30% in advance to start production. After production is finished, we send product photos and inspection reports. Then the customer pays the remaining 70%, and we arrange shipment right away.

If needed, the 70% payment can also be made after seeing the copy of the bill of lading.

L/C (Letter of Credit) is backed by banks and is mainly used for large orders (usually over USD 50,000) or first-time cooperation. It is also suitable for customers in regions like the Middle East or Africa. We support both sight L/C and usance L/C. This method helps reduce risk for both sides.

For custom-made valves or small special orders, we usually ask for 100% payment in advance. After the contract is signed and payment is received, we start production. This allows faster scheduling and shorter delivery times.

3. What are the transportation methods of gas ball valves?

For gas ball valve orders, we offer different shipping methods: sea, air, land, and express delivery.

Sea shipping is best for large orders, including full containers or LCL. Delivery usually takes 30–45 days and has the lowest cost. We use strong packaging and marine insurance to keep goods safe. This method is used for most overseas markets.

Air shipping is used for urgent orders or for landlocked countries. Delivery time is about 7–15 days.

Land transport is suitable for nearby countries. By truck or rail, delivery usually takes 15–25 days, with simple customs procedures.

International express is mainly for samples or small orders. Delivery takes 3–7 days, with door-to-door service and online tracking.

All shipments come with standard export documents. We help customers choose the best shipping plan based on order size, delivery time, and destination market.

4. Does the handle of the gas ball valve support the locking function?

The handle of the Plumberstar gas ball valve supports a locking function. A lock hole is reserved at the connection between the handle and the valve body. Customers can lock the handle position with a padlock to avoid the risk of gas leakage caused by misoperation or malicious opening and closing. At the same time, the locking structure does not affect the normal opening and closing operation of the valve. The handle material still maintains the durability of aluminum or brass. Moreover, this customized function can be superimposed with special structures such as antistatic and fireproof.

5. Does the gas ball valve support two-way flow?

The valve supports two-way flow. The ball and seat are designed symmetrically, so there is no need to worry about which way the gas goes when installing it. This makes it easy to fit different pipe layouts and reduces mistakes during construction.

It works well with natural gas, LPG, and other gases at medium and low pressure. The valve seals tightly in both directions, with a very low leakage rate of ≤0.06 ml/min, meeting high industry standards.

6. DN15-DN25 size gas ball valve operating torque is how much?

DN15-DN25 specifications of gas ball valve operating torque are strictly controlled to ≤5N·m. The torque design is based on the optimized combination of a brass body and PTFE sealing material, paired with a lightweight aluminum butterfly handle, allowing for quick manual opening and closing without the need for additional tools. At the same time, the torque value has been verified under many working conditions.

7. Is the sealing material of the gas ball valve resistant to long-term corrosion of the gas medium?

Gas ball valve sealing material with gas medium long-term corrosion resistance. The valve seat and valve stem packing are made of PTFE, reinforced PTFE, or high-temperature-resistant expanded graphite and other special materials, which can withstand the corrosion of natural gas, liquefied petroleum gas, artificial gas, and other common gas media. Long-term contact will not cause swelling, aging, cracking, or other problems. The expanded graphite material is further adapted to special conditions such as high temperature and high pressure to ensure stable sealing performance.
