Ball valve TN, 1/4 ", with drive-ED, DW43, brass/PTFE-FKM, T-bore, double-acting

3-way ball valve made of brass for shut-off of neutral gases and liquids (no steam) with directly mounted pneumatic double-acting actuator. The body consists of a multi-part screwed body construction, not crossover-free, sealed on all ports, with reduced bore and all-sided female thread. The mounting pad according to ISO 5211 allows direct assembly of pneumatic or electric actuators.

The operation of the ball valve ensued by 90° rotation of the actuator. An actuator with 180° rotation angle and three switching positions 0°-90°-180° is also available on request. If not otherwise stated, we will provide switching position 1 (T-configuration) or 5 (L-configuration) at driven ball valves.

Operation methods:

Due to the twin-piston system the force developed by the counter-running pistons is transmitted to one common pinion via two tooth racks solidly connected with the pistons. This principle ensures a linear torque transmission along the entire stroke.

For higher temperature ranges over +80°C please refer to the Pressure-Temperature-diagram in the data sheet.

The ball valve is also available in many versions in our shop.

• L- or T- configuration
• manually operated
• manually operated with mounted limit switch box
• pneumatically operated with mounted pneumatic actuator, double or single acting
• electrically operated with mounted electric actuator
