Frequently Asked Questions (FAQ)
Q: What is the typical installation orientation for the HVX‑300 valve?
A: The valve can be installed in any orientation, but vertical installation with the actuator above the valve body is recommended for optimal performance.Q: Can the HVX‑300 be used in hazardous (explosive) environments?
A: The standard version is not ATEX/IECEx certified. However, a non‑sparking actuator option is available upon request. Please consult our sales team for specific requirements.Q: What maintenance is required for the pneumatic cut‑off valve?
A: We recommend annual visual inspection and functional testing. Lubrication of the actuator stem is advised every 6 months. Replace seals every 2–3 years depending on operating conditions.Q: Does the valve require a constant air supply to stay open?
A: Yes, the spring‑return design requires continuous air pressure to keep the valve open. In case of air loss, the valve automatically closes (fail‑safe closed).Q: What is the minimum operating pressure for reliable closing?
A: The valve requires at least 0.5 MPa (73 psi) to ensure quick and complete closure. Lower pressures may result in slow response.Q: Can I get the valve with a position indicator or limit switch?
A: Yes, mechanical or proximity position indicators are available as optional accessories. Please specify when ordering.Q: What port sizes are available for the HVX‑300?
A: Standard sizes range from DN50 to DN150. Custom sizes up to DN200 can be manufactured with extended lead time.Q: Is the valve suitable for natural gas engines?
A: Yes, with appropriate seal material (Viton) and optional explosion‑proof actuator, the HVX‑300 can be used in gas engine applications. Always verify compatibility with your specific gas composition.
