Close Bonnet Low Lift Safety Relief Valve for Industrial Gas and Liquid Systems.

Hants Model HSM, A closed bonnet low lift safety relief valve is a fail-safe device for industrial systems that automatically opens to vent excess pressure, but with a sealed bonnet to prevent toxic or flammable media from escaping and to keep contaminants out, suitable for liquids and gases, featuring a disc that lifts proportionally (low lift) to relieve pressure and re-seats when pressure drops, protecting equipment from overpressure.

Hants is a sub-brand of us. As a specialized manufacturer of close bonnet low lift safety relief valve and fittings, we provide reliable pressure relief and overpressure protection solutions for various industries.

Frequently Asked Questions(FAQ) about Close Bonnet Low Lift Safety Valve?

Q: How engineer choose material for low lift safety valve?

Engineers select materials for low lift safety valves by analyzing the fluid's properties, operating temperature and pressure, and required mechanical strength, while also considering corrosion resistance and cost. Materials like bronze are common for general steam/air/water applications at lower pressures, while stainless steel is used for corrosive fluids or clean steam, and special alloys are employed for high-temperature or hazardous gas services.
