Eaton Integrated Check Valves

Eaton Integrated check valves are direct- or pilot-operated check valves for cartridge or in-line hydraulic circuit applications.

Direct-operated check valves can be used as conventional check valves or as low-pressure relief valves. Meanwhile, pilot-operated check valves can be used as position load-locking valves or as an alternative to some counterbalance valves.

The valves have a unique, compact design and deliver low pressure drops for excellent repeatability and stability. The range includes simple, cost-saving load-bearing devices through to optional adjustable override releases.

Eaton check valves can be used as a low-cost alternatives to more complex solutions. This is useful when overrunning loads and/or load release control speed are not factors. A 3:1 pilot ratio satisfies simple load holding requirements, while providing smooth operation and longer operating life.

Other features of Eaton Integrated check valves include:

• Low spring settings;
• Pressure rating up to 350 bar (5,000 psi);
• Flow rating up to 227 litres / minute;
• Wide variety of standard housing and port options and BSPP port options in the following configurations: In-line single or dual | SAE, 4-bolt, code 61 | Close coupled, nipple mounted | Gasket mounted single or dual

All of Eaton’s check valve cartridges have hardened and ground poppets and sharp-edged ground steel seats, which provides durability, dirt tolerance, reliable seating and fast cycling.
