Frequently Asked Questions (Q&A):
Q: Can this valve be easily automated with an actuator?
A: Yes. This valve features an integrally cast ISO 5211 high mounting pad. This “high platform” design allows for the direct mounting of electric or pneumatic actuators without the need for secondary mounting brackets or drive couplers, reducing hysteresis and installation time.
Q: What piping standards is this threaded valve compatible with?
A: The valve is highly versatile and can be machined to meet multiple global threading standards, including ASME B1.20.1 (NPT for North America), BS21 (BSPT), DIN 2999/259, ISO 7/1, ISO 228/1, and JIS B0203. Ensure you specify your required thread type when ordering.
Q: Is this valve suitable for flammable or hazardous fluid applications?
A: Absolutely. The valve is designed and tested to API 607 Fire Safe standards. In the event of a fire that destroys the primary soft seals, the valve is engineered to provide a secondary metal-to-metal seal to prevent hazardous fluid leakage. It also features anti-static properties and a blow-out proof stem.
Q: Can I perform maintenance on the valve without cutting it out of the pipeline?
A: Yes. The 3-piece bolted body design allows you to remove the body bolts and “swing out” the center section containing the ball and seats. This allows for quick, inline replacement of internal seals without disturbing the threaded pipe connections.
Q: What is the operating temperature limit for the standard seals?
A: The standard seats are made of PTFE/RPTFE, the packing is pure PTFE, and the stem O-rings are Fluorine rubber. While specific limits depend on the pressure and media, PTFE/RPTFE configurations generally perform exceptionally well from -20°C up to 180°C.
Q: What sizes are available for this specific model?
A: This model is manufactured in a wide range of nominal diameters (DN), starting from 1/4″ up to 4″. Detailed dimensional charts (L, H, M, Ø1, Ø2, etc.) are available for every size to assist your engineers with exact pipeline modeling.
