 Ductile Iron Pressure Sustaining Relief Valve Stainless Steel 304 Pilot Operated ​EPOXY Coated

 

 

 

Description:

 

A500 opens immediately when the pressure in the pipeline is over the safe level, thus relieving excessive pressure from the network. When the pressure returns to normal, the valve will close slowly, at an adjustable speed.

 

The valve can also maintain upstream pressure, regardless of flow rate variations. The valve will be in the “closed” position if the upstream pressure drops below the set-point and will fully open when the upstream pressure exceeds the set-point.

 

 

Pressure Rating: PN10,PN16,PN25,ANSI standard

 

Features:

 

• Non slam operation
• Simple and reliable design
• Easy installation and maintenance
• Low Resistance and high flow capacity
• Protection for sewage as well as clean water pumping systems
