European CE Certification - Relief Valve (Proportional Type)
  • European CE Certification
  • Scope of CertificationRelief Valve Proportional Type
    Certificate Date2021. 08. 31.
    Certificate No.0425 ATEX 004600-00
    Issuing OrganizationICIM S.p.A.
Relief Valve - Proportional Type 1,000psi ~ 15,000psi
Proportional type is a progressively opened as the system pressure increase. It is useful in the system which the pressure increase rapdly or in the high flow system due to vent flow is increased as much as system pressure is increased.

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 back pressure occurs at the drain port.
Corrosive liquids or gases that can damage the valve
High corrosive fluids, liquid N2 or any other fluids that defect the valves.

High Pressure Relief Valve Valve - dimension
- The pressure of inlet port effects set pressure.   
- Turn right to increase set pressure.
- Turn left to decrease set pressure.
High pressure fluid handling components for the chemical, petrol chemical, water-jet, research and oil and gas industries.
The soft seat and large orifice size ensure stable ejection.
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.
