Swagelok SS-MPC-DP-2-C Diaphragm Valve Module

Swagelok SS-MPC-DP-2-C is a 2-port normally closed diaphragm valve module from Swagelok’s Modular Platform Components (MPC) line, built around the DP Series springless diaphragm valves for high-performance gas handling. The 316L stainless steel body houses a cobalt-based superalloy (UNS R30003) diaphragm and a PCTFE seat, enabling ultrahigh-purity service and broad chemical compatibility. It is pneumatically actuated, rated for up to 250 psig (17.2 bar) and temperatures from 0 to 150°F (−17 to 65°C), with a flow coefficient (Cv) of 0.10 to provide controlled flow in compact manifolds. The SS-MPC-DP-2-C is designed for surface-mount configurations and can be integrated into modular gas systems or multiport manifolds, with an optional electronic position sensor for feedback on valve position. The device uses a 1/8-27 NPT air inlet for actuation, and its normally closed configuration means the valve remains sealed until pneumatic actuation opens the flow path. Common applications include semiconductor gas delivery, analytical instrumentation gas lines, and other ultrahigh-purity gas networks where cleanability and material compatibility are critical. As part of Swagelok’s MPC family, this 2-port NC module offers a compact, scalable building block for custom gas-panel architectures in ultrahigh-purity environments.
