STNC TG2311H-06 2-Position 3-Port Push-Pull Pneumatic Hand Pull Valve

The STNC TG2311H-06 is a push-pull operated pneumatic directional control valve, designed for manual on/off and flow direction switching in compressed air systems. As a standard model in STNC’s TG series hand valve lineup, it delivers stable and reliable control performance for both stationary industrial equipment and mobile construction machinery.

This valve features a 2-position 3-port configuration, fitted with an extended mushroom head actuator. The design allows quick, positive operation even when the operator wears thick work gloves. The push-pull action provides clear tactile feedback between positions, effectively reducing the risk of misoperation in field working environments.

In the construction machinery sector, this hand pull valve is most commonly used as the PTO (Power Take-Off) air control switch on truck cranes and hoisting equipment. It also serves as a manual directional control element in pneumatic circuits where electrical control is not available, or where manual override is required for safety purposes.

The valve body is made of aluminum alloy with an electrostatic spray finish, providing scratch resistance and impact tolerance suitable for harsh job site conditions and equipment cabinet installations. The standard G1/8 port size matches globally available pneumatic fittings and tubing sizes, supporting direct installation and replacement on existing equipment.
