PD Series
PD SeriesPDS (Pneumatic Double Acting Scotch Yoke) is an extruded anodized aluminium actuator designed for robust on/off applications. It utilizes a Scotch Yoke mechanism to deliver higher torque at both start and end positions, operated by an air source.
PD Series feature a one-piece body with a molded-in seat to increase the products pressure rating and ability to operate in higher velocity applications. The 3W/3L offers a high-strength through stem design utilizing an internal disc to stem connection to reduce hysteresis.The Series 3W/3L is engineered to provide bidirectional bubble-tight shutoff and isolation of the line media from the stem or valve body. Available in Buna-N and EPDM elastomers as well as Nylon Coated and stainless disc materials it offers a solid platform for a variety of applications. The ISO 5211 top flange allows for easy automation to pneumatic or electric actuation for on/off or modulation applications.
