APPLICATION
Safety relief valve SVOP-K is used for relieving pressure of system in which is beeing installed. It’s simplicity and reliability makes it perfect safety valve for almost every system or fluid.
Accuracy and valve performance stays permanent even on heavy duty demands. Due to simple design makes it easy to perform service and calibration.
DESIGN FEATURES
Safety relief valve SVOP-K is angled type of valve, with thread end connection for exhaust pipeline. It automatically opens and relief limited volume of gas, and automatically closes when pressure normalizes in the system it secures.
Safety valve acts directly according to the developed force, as a result of gas pressure on the plate the set force of the spring is resised. With the adequate increase of pressure, the seat is lifted up to max. 1/4 seat diameter and with this the exiting
conduit is opened.
ON REQUEST:
- special “PP” design for back pressure applications
- connections specified by customer
- every part can be produce to meet customer specification requirements
- special modification for aggressive media
