APV-23 Series 2-way steam valves, DN15–DN50, 0–15 bar

The APV-23 series by Spartan Scientific includes pneumatically actuated 2-way angle valves, specifically designed for the control of air, oil, or steam. These valves use a special Teflon Chevron® seal that ensures separation between the media and pilot sections. In the single-acting normally closed version, the APV-23 uses a spring-loaded pneumatic actuator connected to a sealing disc, which, when retracted, unseats from a precision orifice and allows fluid flow. When pilot pressure is removed, the seat returns to the orifice, and flow stops. The valves feature an ON-OFF indicator on the pneumatic actuator and are suitable for high-temperature liquids compatible with the materials of construction. The body is standard 300 series stainless steel.
