Relief valve opens stem when the pressure exceeds a set pressure and closes when the pressure falls below.
To protect the equipment form the over pressure.
In the system which control the overpressure by heat expansion.
When the low drain rates is not the problem point in high pressure.
When the system requires “bubble tight’ sealing.
Pressure ~ below 1,000psi.
If the system requires to increase venting or drain rates when the pressure rises.
If the back pressure occurs at the drain port.
High corrosive fluids, liquid N2 or any other fluids that defect the valves.


As all sizes are for reference, they can be changed without any notification.
Please contact us for details or send to online inquiry, we will give you respond as soon as possible.

- The pressure of inlet port effects set pressure.  
- Turn right to increase set pressure.
- Turn left to decrease set pressure.
- a tolerance value : ± 8%
High pressure fluid handling components for the chemical, petrol chemical, water-jet, research and oil and gas industries.
Cone and thread connection to prevent gas or liquid leaking.
Our products generally are produced with stainless steel materials, but they can be manufactured with other materials on demand so that various fluids and gases can be used Please inquire with us about special materials apart from the above-mentioned materials, such as STS316, HC-276, Inconel, Titanium, Nickel.
You can choose the handle type. Please leave the desired type in the requirements section when ordering the product.
