Pressure relief-valve
Our premium performance direct spring operated pressure relief valves are specially designed, using special internals and soft seats to provide optimum and accurate performance.
Our pressure relief valves provides overpressure protection from very basic to the most demanding applications.
Backed by over 140 years of engineering and application experience, their versatile and rugged designs will always make a difference proving to be the perfect solution for oil and gas, process and power industry overpressure protection.
GOOD SUPPLIER series are the standard conventional relief valve designs for applications when the discharge is to the atmosphere or to a low pressure system designed to contain the process fluid.
We have the best quality that you can ever find!
This model of pressure relief valve is designed to relieve excess pressure in a fire protection system while eliminating the damaging effects of cavitation.
The valve features an adjustable pressure setting, fast opening to maintain steady line pressure, and gradual closing for surge free operation.
First Series Direct spring operated safety valves suitable for medium set pressure gas, vapor and liquid or gas thermal relief applications. Brass construction offers an economical valve for carbon dioxide, natural gas and general gas or vapor services.
Second Series Direct spring operated safety valves suitable for premium performance. They use special internals and soft seats to provide optimum, accurate performance.
Ideal for Onshore and Offshore applications, the anti-cavitation trim seat will reduce pressure relief valves will protect against cavitation, reduce noise and vibration and will extend the valve life.
Product Feature
- Soft seat design provides repeatable bubble-tight performance before & after each relief cycle.
- Leak-tight performance near set pressure allows higher operation pressure, resulting in increased process troughput and system optimization.
- Easily replaceable soft seat and seals eliminate expensive, time-consuming lapping of metal components, resulting in lower long-term maintenance costs.
- Extremely adjustable blowdown allows precise adjustment. Blowdown can be adjusted with valve in service, helping eliminate the need for costly removal and/or system shut down.
- Provides full lift set pressure with no overpressure required. Minimizes possibility of freeze-up in applications involving a cryogenic or refrigerant and allows for D.O.T applications to be set higher than Maximum Allowable Operating Pressure.
- Spindle design balanced against the effects of back pressure without the use of a bellows, reducing both initial purchase and associated long-term maintenance costs.
- Meet ASME Section VIII requirements, providing the user with third party verification of valve capacity and performance.
- Ideal for applications with high pressure differentials.
- Meets flow requirements set forth by applicable approval agencies.
- Provides a safer work environment by preventing valve damage.
- Comply with the EC Pressure Equipment Directive 97/23/EC.
