Ross Controls 2751A4922 Check Valve

Ross Controls 2751A4922 is a 27 Series Pilot Operated Check Valve designed for inline mounting in pneumatic circuits where safe, controlled actuation of a check valve is required. It is a 2-Way, 2-Position valve with pressure-controlled ports that uses a pilot signal to govern the main check valve action, enabling a cylinder to be held or released under control without loading the main supply. This model features a dedicated pilot/signal port sized at 1/8-27 NPT, and the unit’s documented weight is approximately 1.8 kg. As part of the 27 Series, the 2751A4922 is cataloged for safety-related use (Category 1 PL c) and can be configured with or without pressure relief depending on installation needs. The valve is designed for inline installation in standard industrial pneumatic systems and is referenced in Ross Controls’ safety-related product literature and 27 Series PO Check Valve listings.
