FAQs of Gas Ball Valve

1. Can you provide gas ball valve with 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 B2B trade in gas ball valves, adapt to different order amounts, cooperation stages, and customer demands, and provides a variety of safe and compliant payment methods.

T/T, Telegraphic Transfer, is the most commonly used mainstream payment method in foreign trade transactions of Plumberstar gas ball valves. A flexible payment ratio is often adopted in cooperation. The normal payment is a 30% advance payment as production start-up capital. After we complete production and provide stock photos and quality inspection reports, customers pay the 70% final payment. We arrange delivery immediately after receiving the final payment; we can also negotiate the payment mode of 30% advance payment plus 70% seen in the bill of lading copy.

L/C, Letter of Credit, is guaranteed by bank credit, suitable for large gas ball valve orders (such as single purchase amount ≥ 50,000 US dollars) or initial cooperation with new customers, especially suitable for customers in politically and economically unstable regions such as the Middle East and Africa. We support sight L/C and usance L/C. Customers can choose according to their needs. This method can greatly reduce the risk of trading between both parties.

100% Advance Payment for customized gas ball valve orders or small quantities of scarce gas ball valve orders. After signing the contract, the customer pays in full, and we start production. This method has zero risk for us, and at the same time allows us to prioritize production scheduling, shorten the delivery cycle, and ensure rapid order advancement. It is suitable for customers who have high requirements for delivery efficiency and pay attention to cooperation sincerity.

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

For our gas ball valve foreign trade transportation mode covers sea, air, land and international express:

sea adapt to large quantities of orders (whole cabinet/LCL), aging 30-45 days, the best cost, through reinforced packaging + marine insurance to ensure long-distance transportation safety, covering the global coastal market;

air for emergency orders or inland countries, aging 7-15 days, relying on well-known shipping company direct, supporting customs clearance assistance services;

Land transportation is suitable for neighboring countries, with railway/road transportation timeliness 15-25 days, convenient customs clearance;

international express adaptation sample list, timeliness 3-7 days to door delivery, real-time logistics tracking.

All shipments are provided with standardized customs clearance documents, and the best solution can be tailored according to the order size, timeliness requirements, and target 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?

Support a two-way circulation function. The ball and valve seat adopt symmetrical sealing layout, no restriction on inlet and outlet direction, no need to deliberately distinguish the flow direction of medium during installation, flexible adaptation to different pipeline layout requirements, reducing the risk of misoperation during construction, ensuring excellent sealing performance and circulation efficiency when natural gas, liquefied petroleum gas and other gas media flow in both directions under medium and low pressure conditions, and the leakage rate is strictly controlled at the industry high standard of ≤0.06ml/min.

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 gas ball valve resistant to long-term corrosion of 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.
