Safety Valves / Pressure Relief Valves

An extensive stock of safety valves for equipment of all kinds!

Safety Valves — also referred to as Safety Relief Valves and Pressure Relief Valves — are machine parts that automatically open to control or limit building pressure from air, gas, steam or liquid.

Too much pressure can interfere with a process or even lead to equipment or instrument failure. That’s why you want to make sure you’re using Kingston Safety Relief Valves, which set the standard for durability and performance.


SVI’s selection of Kingston Safety Relief Valves includes American Society of Mechanical Engineers (ASME) code valves and non-code valves for air, gas, steam and liquid.

All Kingston ASME Safety Valves are manufactured to national board requirements for pressure relief devices according to the ASME Boiler & Pressure Vessel Code (BPVC) Section VIII, Division I.

Kingston Safety Valves are common in industrial, medical, vehicle-system and agricultural applications. They often prevent over-pressurization in compressed air or steam systems such as air compressors, air lifts, air dryers, air tanks and steam sterilizers.

Available in both brass and stainless steel, these valves range in inlet size from 1/8” to 1” and set pressure from 1 to 600 PSI. We also provide you with options for National Pipe Thread (NPT), British Standard Pipe Thread (BSPT), oxygen service, and various seat and disc materials.

Sooner or later, any machine that works hard will have parts that need replacing. When it’s a matter of preventing too much pressure, you can’t afford deficiency. SVI’s extensive access to premium valves ensures you can acquire the exact part for your air, gas, steam or liquid application. Better still, we can ship it to you fast from one of our regional warehouses.

Our service to you extends well beyond that. In addition to Safety Valves, we offer all types of Kingston Valves including Control Valves, Ball Valves, Check Valves and more.
