If the pressure at port 1 exceeds the pressure setting,
the pilot poppet opens, creating a small
flow over the orifice of the pilot stage to
the tank. The pressure drop across the
orifice lifts the main spool against a light
spring, opening the connection between port 1 and port 2.
z Excellent stability throughout the entire flow range
z Low pressure drop due to CFD optimized flow path
z Screen protected metering orifice enhances safety
z Optional spring ranges up to 345 bar
z Adjustable throughout flow range
z Quick response
z Compact design
External surfaces zinc-plated and corrosion-proof
z Hardened and ground internal valve components to ensure minimal wear and
