FAQs of Butterfly Gas Ball Valve

1. What are the main materials used for Plumberstar butterfly gas ball valves?

Plumberstar butterfly gas ball valves have main bodies made of brass (H59/H62) and stainless steel (304/316). Their seals are made of nitrile rubber (NBR) and fluororubber (FKM). These seals resist gas corrosion. The valve core is made of copper alloy or stainless steel. All materials have passed the gas contact safety test and meet the safety standards of gas valves, such as GB 15558.1 (national standard), EN 331 (Europe), and ANSI Z21.15 (USA). No harmful substances are precipitated.

2. What are the opening and closing methods of the butterfly gas ball valve?

There are mainly manual opening and closing (handle type), electric opening and closing (electric actuator), pneumatic opening and closing (pneumatic actuator), three kinds. Manual handle rotation 90° to complete the opening and closing, with a limit device, labor-saving operation; electric/pneumatic models support remote control, adapt to automatic gas system, according to customer needs to configure actuator brand and control mode.

3. What is the sealing performance of the Butterfly Gas Ball Valve?

Double seal structure-hard seal (metal to metal)+ soft seal (seal and valve core fit), gas leakage ≤0.01cm³/min (in accordance with ISO 5208 Class VI seal standard) Before each valve leaves the factory, air tightness test (1.5 times rated pressure for 30 minutes) is performed to ensure no gas leakage, and safety is guaranteed from both structure and detection.

4. What types of gas are butterfly gas ball valves suitable for?

It works for natural gas (NG), liquefied petroleum gas (LPG), artificial gas (CG), methane, and other common gases. It can also be used for non-corrosive, low viscosity gas or liquid (like air, inert gas, light oil). You need to specify the medium type in advance. This helps match the sealing material. For example, a corrosive medium needs fluororubber sealing.

5. How to select Butterfly Gas Ball Valve size according to gas flow?

The core of selection is to ensure that the valve diameter ≥ the gas pipeline diameter, and the valve flow coefficient (Cv value) meets the pipeline flow demand. General reference: DN15 is suitable for flow ≤5 m³/h, DN25 ≤ 15 m³/h, and DN50 ≤ 50 m³/h. If it is an industrial high-flow scenario, pipeline pressure and flow parameters can be provided. Plumberstar engineers assist in making accurate selections to avoid waste caused by insufficient flow or excessive valve usage.

6. What are the customization requirements for butterfly gas ball valves supported by Plumberstar?

Customization supports special alloy materials with anti-corrosion coatings, as well as large diameter (DN100 and above) specifications, thread and flange mixed connections, emergency shutdown, remote control, flow metering functions, surface treatments, and customer logo engraving on the exterior.

7. What is the warranty period for the butterfly gas ball valve?

Standard warranty period is 24 months (longer than the industry’s 12-month standard), starting from the customer acceptance date. It covers material defects (such as cracking, rust, and non-artificial damage), the valve manufacturing process issues (including loose sealing, opening and closing failure), and aging seals (with free replacement). Free new product replacement or maintenance is provided within the warranty period.

8. What is the packing method for export?

Conventional export standard packaging (inner pearl cotton + outer plywood wooden case, in line with ISPM 15 fumigation standards), each valve is packed independently to avoid transportation damage; can be customized valves according to customer requirements: 1. Neutral packaging (Without Plumberstar manufacturer informations). Wooden case/carton: Print customer logo, brand name, and warning logo.

9. How to detect whether there is a gas leakage valve?

Detection method: 1. Soapy water detection: smear soapy water on the valve interface and the valve core. If bubbles are generated, it indicates leakage;2 Professional instrument detection: use a gas leakage detector (such as a combustible gas detector) to detect, and the leakage concentration shall be lower than 10% of the lower explosion limit. Regular inspection cycle: once every 6 months for home scenarios and once every 3 months for commercial/industrial scenarios to ensure safety.
