Design features:

Simple structure, only a durable, non metal valve plate

Wide groove, valve being blocked the possibility of a smaller

Allows the lift, the effective flow area of the greater, energy saving

Surface processing of the valve cover, more resistant to oil viscosity, longer service life

High performance impact PEEK valves, valve seat, valve wear a small, low noise

Stout spring, low stress, long service life

Applicable conditions:

Large molecular weight: MW>5

In the condition of low pressure

Low speed: speed <1000rpm

Oil / oil free condition
