CIT Series Industrial In-line Threaded Check Valves

Product Overview: The CIT Series Check Valve features an in-line threaded design and is an indispensable safety component in hydraulic piping. Its core function is to allow free fluid flow in one direction while providing an absolute seal in the opposite direction. With its compact structure and extremely low cracking pressure, this series is widely used in industrial power units, machine tool hydraulic systems, mobile machinery, and any hydraulic circuit requiring backflow prevention.

We offer the complete range from CIT-03 (3/8″) to CIT-16 (2″), ensuring compatibility with flow requirements ranging from miniature laboratory systems to heavy-duty industrial presses.

Key Technical Advantages:

• Low Pressure Drop Design: Hydrodynamically optimized internal poppet structures ensure minimal heat generation and energy loss even during high-flow operations.

• Absolute Sealing Integrity: Precision-ground and hardened poppets and seats guarantee a zero-leakage, metal-to-metal seal in the reverse-closed position.

• Simple Installation: Utilizing standard inline threaded connections (BSPP or NPT), these valves can be installed directly into the piping without subplates, significantly saving space.

• Superior Durability: Rated for operating pressures up to 21 MPa (210 Bar), designed to withstand frequent pressure spikes within the system.
