The AIDEKE PA Actuator Pneumatic Angle Seat Valve is a 2/2-way on/off valve with a PA (polyamide) actuator and stainless steel 316/304 body. It is designed for controlling liquids, gases, and steam in industrial applications.

Working Principle

In the non-actuated state, spring force keeps the valve in its default position (normally closed or normally open). When compressed air is applied to the actuator piston, the valve switches state. Both single-acting (spring return) and double-acting versions are available, with flow direction over the seat.

Applications

This valve is widely used in beer and beverage filling, printing and textile industries, gas processing, pharmaceutical and medical equipment, chemical processing, high-temperature sterilization, foaming machinery, wastewater treatment, and rubber machinery.

Dimensions

Available sizes range from DN10 to DN50, with actuator diameters of 50mm, 63mm, 80mm, and 100mm. Overall height (H) ranges from 138mm to 271mm depending on size and actuator.

Model Selection

Models are identified by a code such as A7115xxx-xx (normally closed, single acting), A7114xxx-xx (normally closed, double acting), and A7119xxx-xx (normally open). The code indicates orifice size (13–50mm), connection thread (G3/8 to G2), and actuator size (50–100mm). Kv values range from 3.7 to 49.0 m³/h. Working pressure is generally 0–1.6 MPa, with control pressure between 0.2–0.9 MPa depending on the model.

Key Features

Long service life with robust and compact construction. Suitable for high-temperature media up to 180°C. Versatile mounting orientation. Wide range of port sizes and actuator options.
