KVV Low Lift Stainless Steel Relief Valve (1/4″~1/2″)

 

Uses
● Intended for limiting system pressure, thereby preventing system pressure from exceeding the preset safe value (set pressure);
● KVV relief valves can be used for neutral or slightly corrosive liquids and gases.

 

Features
● 
Low lift structure, applicable to liquids and gases with low emissions
● Direct acting construction, flexible valve operation
● Set pressure adjustable
● Straight shape, compact construction

 

Operating Principle: When inlet end pressure goes beyond the set pressure, it overcomes the spring force and opens the disk, and the medium at the inlet end is discharged via the relief valve to the outlet end, thereby controlling the inlet end pressure within the set range. The outlet end generally connects a vent, or it will affect pressure relief. When system pressure falls below the re-seating pressure, the disk and the seat close.

 

Note: KVV relief valves are used in common pressure relief applications to prevent over-pressure, but not used as relief valves defined in pressure vessel design standards.
