The Spartan Scientific Series APV-20 is a 2-way, 2-position valve specifically designed for the control of steam. The APV-20 uses a specially designed Teflon Chevron® seal which ensures separation of the media and pilot sections. In the single acting normally closed version, the APV-20 uses a spring extended pneumatic operator connected to a sealing disc which when retracted, unseats from a precision orifice and allows fluid flow. When pilot pressure is removed, the APV-20 seat returns to the orifice and flow stops. A feature of the APV-20 is the ON-OFF indicator at the top of the pneumatic actuator. The APV-20 can be used for high temperature liquids compatible with the materials of construction and steam. The bronze body is standard and is available in sizes ranging from 1/2" to 2" NPT and can control media up to 300 psi. Also available is a three way solenoid pilot valve (Spartan Series 3823), which may be added to operate the APV-20. Consult factory for details
