Overview
The PR P/S OF pneumatic corrosion-resistant O-shaped ball valve consists of two components: a PR light and small corner actuator and a corrosion-resistant O-shaped cut-off ball valve. The PR light and small angular actuator is designed with two pistons in one cylinder, whose thrust is transmitted to the central gear through the rack to form torque, driving the output shaft to rotate; This type of actuator has a compact structure, high output torque, smooth and reliable transmission, and long service life.

1、 Overview
The PR P/S OF pneumatic corrosion-resistant O-shaped ball valve consists of two components: a PR light and small corner actuator and a corrosion-resistant O-shaped cut-off ball valve. The PR light and small angular actuator is designed with two pistons in one cylinder, whose thrust is transmitted to the central gear through the rack to form torque, driving the output shaft to rotate; This type of actuator has a compact structure, high output torque, smooth and reliable transmission, and long service life.
Corrosion resistant O-shaped ball valve, with high-pressure injection molding process used for the inner cavity of the valve body and the inner and outer surfaces of the ball body, lined with perfluoroalkoxy (F46), with a thickness of 2.5-3mm; The valve seat is made of tetrafluoroethylene, which can resist the corrosion of various acids, alkalis, oxidants and aging. Therefore, the corrosion resistant ball valve is named (also known as plastic lined O-shaped ball valve).
Due to its corrosion resistance and advantages such as low resistance and high leakage level, the O-shaped ball valve is widely used in industrial sectors such as chemical, petroleum, metallurgy, and medicine to control various highly corrosive media. It is often used as a shut-off valve and can also be used for proportional adjustment if equipped with a valve positioner.
