It is the only check valve on the market with both manual and pilot release capabilities. https://www.pneumadyne.com/pilot-operated-check-valves-p-14117.html Pilot Operated Check Sensing Valves SV27 Series - SV27DC555405ASAA - ROSS Controls With Sensing & External Monitoring 1-800-438-7677 Available port sizes are 1/8", 1/4", 3/8" or 1/2" NPT with flow coefficients (Cv) from 0.67 to 2.79. Designed for use in applications requiring an actuator to be locked in position, Pilot Operated Check Valves allow free flow from the input port through the output port. JIS symbol of pilot check valve . These rugged valves feature a 1/4 NPT output port which mounts directly on a cylinder, minimizing space requirements and easing tubing installation. The unique bubble - tight seal keeps devices in "checked" position. Size 10, 16, 25 (4W.H22), 25 (4W.H25), 32; Component series 4X, 7X, 6X; Maximum operating pressure 280 bar; Maximum flow 1100 l/min; They will revert to the rest position as soon as pilot pressure is removed. This allows the use of standard shop air pilot (50-150 psi). The Clippard Pilot-Operated Check Valve provides the user with a reliable method to check flow in one direction, with the ability to remotely signal a free flow through the valve. This reduces the wear on the poppet seal and allows the pneumatic check valve to operate at higher pressures, Hardcoat anodized aluminum with lubricant coating to reduce wear and increase seal life, Manual release buttons (extended length or flush buttons) to exhaust trapped air in cylinders prior to system maintenance, Flow control, which meters air from the output to the input port to avoid crash landings or equipment crashes, Available lower pilot pressure options enable trapped air to pilot pressure ratio of 4:1.
