Pnuematic Actuators: Double-Acting Type PD

PD model pneumatic actuators are designed and produced in Scotch-Yoke mechanism. These operators have the ability to operate or change the status of quarter-turn valves such as ball valves and butterfly valves. The advantage of this model of actuators is high torque production.

Features

Can be used in natural gas, nitrogen, air and etc Services
Compliant with IGS, IPS and API 6DX standard requirements
Design with Scotch-Yoke mechanism suitable for quarter-turn valves
Use of high engagement level rollers to transfer power without slipping
Converting linear force into rotation in a chamber separate from the pressurized cylinder, which enables the use in services with a risk of explosion
