常见问题
What is the difference between double offset and triple offset butterfly valve?
Double offset valves are widely used for reliable shut-off in water and industrial systems. Triple offset valves are often selected for higher temperature, metal sealing or severe service conditions.
What is the working temperature range?
The working temperature depends on seat and body material. Common options cover -20°C to 180°C, with higher temperature designs available on request.
What are the available connection types?
Wafer, lug, flanged and other connection types can be supplied according to project standards.
Can the valve be used for bi-directional flow?
Many JQH butterfly valves can support bi-directional flow. Final selection should be confirmed with size, pressure and sealing requirements.
Can you provide custom design and OEM service?
Yes. JQH Valve supports OEM marking, custom materials, actuator packages, export packing and project documentation.
