- Lock-up valve used to shut off the signal pressure line of pneumatic actuators.
- Switching accuracies are 3 psi for 30psi, 4.5 psi for 60 psi, and 6 psi for 90 psi.
3709 - Pneumatic Lock-Up Valve
The Type 3709 pneumatic lock-up valve is designed to work in all general industrial applications. The lock-up valve is used to shut off the signal pressure line of pneumatic actuators either when the air supply falls below an adjusted value or upon complete air supply failure. This causes the actuator to remain in its last position.
