Swagelok Company MH3760001 Pneumatic Actuator

The Swagelok MH3760001 is a 90-degree, spring-return pneumatic actuator from Swagelok’s 155 Series designed to convert compressed air pressure into a precise, single-stroke rotation for valves and other process devices. It is the MS-155-SR model, rated for a maximum supply pressure of 200 psi (13.7 bar), delivering reliable 90° actuation with a compact footprint and an internal volume of 30.5 in³ that supports mid-sized Swagelok ball valves. In standard service, it operates over a temperature range of −20 to 200 °F (−28 to 93 °C) and weighs about 12.5 lb (5.7 kg), enabling robust performance in challenging environments while providing fail-safe spring return. The MH3760001 variant aligns with the 155-series spring-return lineup and is designed for mounting on valves and components with compatible patterns, offering straightforward installation and consistent actuation in automated systems that require a reliable, limited-stroke 90° rotation.
