Type 14450

Types 14520 – 14580

Type 14340 low pressure

14540, 14640 semi-capsule

Accurate pressure control – up to 100 bar
Low internal friction – reseating at 90% cracking pressure
Large seat area gives long life and repeatability
316 stainless steel construction


The Type 14340 low pressure relief valve has been designed to provide accurate pressure control in systems operating at pressures up to 100 bar, such as chemical injection applications.

The low friction internal design produces reseating at 90% of cracking pressure or better.

The valve is constructed from stainless steel and uses chemical resistant polymer materials in the seat to provide good low pressure seating with zero leakage

Large area seat ensures long life and repeatable performance.
