Doering shop air (pneumatic) pilot operated valves provide a simple solution to controlling mediums such as HYDRAULIC oil, NITROGEN or other fluids or gases. Pilot-Operated Check Valves work as standard check valves, but can be opened with an air pilot signal to permit free flow in the normally “checked” direction. Contact a supplier or the parent company directly to get a quote or to find out a price or your closest point of sale. 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. These air operated valves are available with single pilot spring return or double pilot 2-position operation. There are two types of pilot operated check valves: threaded cartridge style and pilot piston style. The Position and Flow Boxes indicate how the valve functions.

Miniature 3-Port Pneumatic Solenoid Valve. Optimal flow capacity in compact spaces required by high-tech device and instrument makers. Pilot Operated Check Valves: Plated for corrosion resistance and features low cracking pressure to speed flow to the ports. Pilot operated check valves work by allowing free flow from the inlet port through the outlet port. The Actuators are the mechanisms which cause the valve to shift from one position to another. CHECK THE EMPLOYMENT MENU ABOVE. The ARO® MaxAir light-duty directional pilot air control valve has aluminum bar construction to resist corrosion. Miniature 2- or 3-Way Pneumatic Solenoid Valves. -K18, 11120 B4S00AD-25 B4S0MAD-25 B4SFMAD-25 B4S00AD-38 B4S0MAD-38 B4SFMAD-38 B4S00AD-50 B4S0MAD-50 B4SFMAD-50 B6S00AD-25 B6S0MAD-25 B6SFMAD-25 B6S00AD-38 B6S0MAD-38 B6SFMAD-38 B6S00AD-50 B6S0MAD-50 B6SFMAD-50 Every valve has at least two positions and each position has one or more flow paths, thus every valve symbol has at least two Flow Boxes to describe those paths. Full range of sizes from micro-mini to 500 GPM. Operating pressure up to 150 psi and flow rates ranging from 5.2 to 22 scfm at 100 psi. For example, 80 psi trapped pressure can be released with as low as 20 psi pilot pressure, Adjustable spring pressure, enabling the valve to close at a higher pilot pressure or before all the air exhausts, resulting in faster stops, Stainless steel is available on certain models. Directional spool valves, pilot operated, with pneumatic-hydraulic actuation WPH. ASP-X369 Series ⋅ Compact 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. When pneumatic pressure is applied to the pilot, the internal valve parts move and the valve will close. B6S00-25, B6S0M-25, B6SFM-25, B6S00-38, B6S0M-38, B6SFM-38, B6S00-50, B6S0M-50, B6SFM-50, You can operate the ARO® compact air pilot directional valve remotely or by using an air pilot signal. Pneumatic Components & Systems Manufacturing This allows the use of standard shop air pilot (50-150 psi). These valves are offered with a wide choice of end configurations and materials. The input port swivels to accommodate valve alignment and contains a 1/4 push-in connection to speed tubing installation. Cartridge Style Valves. The unique bubble - tight seal keeps devices in "checked" position. ASP-X369 Series, XTO Series Intended use: Drop prevention of cylinders and circuit configuration for temporary intermediate or emergency stops (Note) Precise intermediate stops are not guaranteed. New Proportional iDP Valve – 390 and 391 Series. JIS symbol of pilot check valve . We offer many pilot to working port ratios. Most air operated valves will only stay in the applied pilot pressure position while the pilot pressure exists. Our valve options with with lower pilot pressure (-K18), high temp seals (-V), and low temp seals (-T40) are searchable as well as any product number.

The XT34-303 series of pilot operated check valve is a direct mounted model with threaded connections. Supplying a pilot pressure to the pilot port allows flow in the opposite direction. 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. Find out all of the information about the Festo product: pneumatic check valve VBNF. It is the only check valve on the market with both manual and pilot release capabilities. Compressed air flows to and from the drive as long as a control signal is applied to pneumatic connection 21. Pneumatic Air Pilot Valves NITRA® pneumatic AVS-5 series directional pilot control valves are body ported 5-port (4-way) spool valves. A solenoid valve has two main parts: the solenoid and the valve. The pneumatic check valve locks air in the device until the pilot signal is energized, at which time the valve opens and air evacuates the cylinder. Pressure ratings to 6,000 PSI. NGT pilot operated check valves are available in a variety of body configurations, with port sizes ranging from 1/8” to ¾” NPTF. This type of check valve always permits free flow in one direction but permits flow in the normally blocked opposite direction only if the pilot pressure is applied at the pilot pressure point of the valve. 11111 B2M00, B2M0M, B2MFM, B4M00, B4M0M, B4MFM, B6M00, B6M0M, B6MFM, BG4M00-1, BG4M0M-1, BG4MFM-1, BG6M00, BG6M0M, BG6MFM, B2MOO, B2MOM, B4MOO, B4MOM, B6MOO, B6MOM, BG4MOO-1, BG4MOM-1, BG6MOO, BG6MOM, 11112 B4M00FL, B4M0MFL, B4MFMFL, B6M00FL, B6M0MFL, B6MFMFL, BG4M00FL-1, BG4M0MFL-1, BG4MFMFL-1, These rugged valves feature a 1/4 NPT output port which mounts directly on a cylinder, minimizing space requirements and easing tubing installation. BSPP ports are also available. 10-32 (F) and 1/4 push-in ports are available to fit plumbing specifications. When the … Check out our Interactive Pneumatic Circuit Symbo… They control the speed of air-powered equipment by adjusting the volume of airflow. Supplying a pilot pressure to the valve allows flow in the opposite direction.Pneumadyne's Pilot Operated Check Valves are ideal for reliably holding an actuator position in a variety of applications. Air valves are shifted by an air pilot signal. Working port pressure ratings are available up to 5,000 psi on some valves. When pressure to the pilot port is removed, flow occurs in one direction only, due to an integral non-return valve. This output can be used for a confirmation signal in a machine safety scheme. A pilot valve is a small valve that controls a limited-flow control feed to a separate piloted valve. ASP-X352, Speed Control Valve with Pilot Operated Check Valve Series ASP is a speed controller with an integrated pilot check valve. Pilot Operated Check Valve . -K18, -V, -T40, 11122 B8100FL, B810MFL, B81FMFL, B12100FL, B1210MFL, B121FMFL, B81OOFL, B81OMFL, B121OOFL, B121OMFL Electrically Operated Air Directional Control Valves Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. Pilot Operated Check Valves The Nu-Check © Valve, designed specifically for pneumatics, is a patented ALADCO® product. Available in check, relief, shuttle and pilot operated check valves. -K18, 11123 B8100AD, B810MAD, B81FMAD, B12100AD, B1210MAD, B121FMAD, B81OOAD, B81OMAD, B121OOAD, B121OMAD, Balanced poppet design reduces the load on the main poppet seal by pulling the poppet away from the face seal as the pressure increases. They will revert to the rest position as soon as pilot pressure is removed. The solenoid converts electrical energy into mechanical energy which, in turn, opens or closes the valve mechanically.. A direct acting valve has only a small flow circuit, shown within section E of this diagram (this section is mentioned below as a pilot valve).
