Pilot-To-Open Check Valvem CKGB-XCN T-17A
CKGB-XCN - Pilot-To-Open Check Valvem, T-17A: Industrial & Scientific. CKGB-XCN - Pilot-To-Open Check Valvem, T-17A: Industrial & Scientific. Type: Pilot-to-open check 。 Capacity: 60 gpm 。 Seals: Buna 。 Cavity: T-17A 。 Control: Standard pilot 。 This valve is a pilot to open check valve. It has a non-sealed pilot, a steel seat, and is nonvented. It allows free flow from the valve (port 2) to the load (port 1) and blocks flow in the opposite direction. Pressure at the pilot (port 3) will open the valve from port 1 to port 2. Pilot pressure needed at port 3 to open the valve is directly proportional to the load pressure at port 1. Pressure at port 2 directly opposes pilot pressure. Technical Features Provides hose break protection, prevents loads from drifting and positively locks pressurized loads. This 3 port pilot-to-open check valve and 3 port counterbalance valves are physically interchangeable (i.e. same cavities, same flow path for a given frame size). However, cartridge extension dimensions from the mounting surface may vary. Standard unsealed pilot allows air trapped in the pilot line to be purged from the circuit. For models with manual load release control option, turn load release clockwise to release load. Extremely low leakage. The seat and poppet are heat treated for long life. If the load drifts due to the valve, the seat has probably been damaged by contamination and the valve should be replaced. Stainless steel cartridge options P or W are intended for use within corrosive environments with all external components manufactured in stainless steel or titanium. Internal working components remain the same as the standard valves. Optional external porting out of the hex end of the cartridge is available for external piloting. In this configuration, port 3 is blocked. See Control options E, and P. Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations. Pilot-to-open check cartridges are locking valves, not motion control valves. For motion control applications, use counterbalance valves. 。 。 。
