HGL series features pilot operated check valves which allow air to flow provided a signal is present at the pilot signal port. If no pilot signal is applied, the valves shut off the exhaust air from the drive. Festo check valves are suitable for use in safety related systems and can be used for short duration positioning and braking of pneumatic actuators. Featuring male thread connections M5, G1/8, G1/4, G3/8 and G1/2. With a flow rate/speed of 130 to 1,400 l/min, these valves are robust and durable.
