Product Overview
The COMPACT C25 SR-2C IMP is a pneumatically actuated industrial process valve designed for precise media control in demanding fluid and gas handling systems. Manufactured by COMPACT, a recognized name in pneumatic and process valve technology, this model utilizes a spring-return (SR) pneumatic actuator with a 2-way, normally closed (2C) configuration. The “IMP” designation indicates an imperial port configuration, making it directly compatible with standard NPT/BSP threaded piping systems common in North American and international industrial installations. The valve operates via a pilot air signal acting on a piston or diaphragm actuator, which drives the valve stem and sealing element to open or close the flow path. Its compact, robust construction allows for reliable on/off isolation and process control in space-constrained manifolds, skids, and OEM equipment where a positive shutoff and fast actuation response are essential.

Engineering Features & Advantages
- Precision Performance: The spring-return pneumatic actuator ensures fail-safe closure upon loss of pilot air, providing reliable process isolation and protecting downstream equipment from unintended media flow.
- Fast Actuation Response: Optimized piston/diaphragm design delivers rapid opening and closing cycles, making the C25 SR-2C IMP suitable for batch dosing, emergency shutoff, and automated sequence control.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, with robust stem sealing and corrosion-resistant wetted parts to withstand aggressive media and high-cycle duty.
- Compact Footprint: The space-saving body design allows dense manifold mounting and integration into OEM skids where installation envelope is limited.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original COMPACT standards, allowing straightforward retrofit into existing hydraulic systems without rework.
