Bellows K065-4033 Valve

The Schrader Bellows K065-4033/403353 solenoid valve is a compact, bellows-sealed pilot valve engineered for precise, leak-tight control of gases in instrumentation and gas-handling lines. The design uses a metal bellows to isolate the actuator from the process media, providing hermetic separation and reducing drift or leakage over time. In verified listings, the K065 family is specified with a 110V AC coil, a 0–140 PSIG working pressure range, and a 3NOI configuration, with JIC Lok fittings for robust, vibration-tolerant connections. Electrical operation is compatible with common 50/60 Hz power, with many catalogs citing 120/60 Hz service. The model is cataloged under K065-4033/403353 in distributor listings and is associated with the Schrader Bellows line that Parker and authorized distributors provide. Some listings indicate compatibility with a manifold option (for example N1952400153 variants noted in listings) to simplify integration into larger control assemblies. Applications include precision gas control in analytical instruments, gas handling systems, and other setups where leak integrity and tight shutoff are critical, making the K065-4033/403353 a purpose-built choice when bellows-sealed actuation and reliable seal performance are essential.
