Product Description
Samson steel Type 3709 positioner Solenoid valve for controlling pneumatic linear actuators
Product Introduction
The pneumatic lock-up valve shuts off the signal pressure line
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.
Special features
The pneumatic lock-up valve shuts off the signal pressure line
either when the air supply falls below an adjusted value or
upon complete air supply failure. This causes the pneumatic
actuator to remain in its last position.
The supply air produces a force on the diaphragm (4) which
is balanced by the spring (6). When the force produced on
the diaphragm is greater than the spring force, input and out
put are connected, i.e. the signal pressure supplied by the po
sitioner is transmitted unobstructed to the pneumatic actuator.
When the supply air pressure falls below the adjusted value,
the spring force dominates, and the spring (6) moves the plug
(3) fully into the seat (9). As a result, the pressure in the pneu
matic actuator is blocked.
Types 3709-4 to 3709-8 are also fitted with a booster to gen
erate higher air capacities. An internal control pressure acti
vates the booster.
