The Spartan Scientific Series APV-23 is 2-way, 2-position valve specifically designed for the control of air, oil or steam The Series APV-23 uses a specially designed Teflon Chevron® seal which ensures separation of the media and pilot sections. In the single acting Normally Closed version, the Series APV-23 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 from the Series APV-23 the seat returns to the orifice and flow stops. Features of the Series APV-23 are the ON-OFF indicator at the top of the pneumatic actuator and can be used for high temperature liquids compatible with the materials of construction and steam. The stainless steel body is standard and is available in sizes ranging from 1/2” to 2.0” NPT and can control media up to 215 psi in various configurations.
