I. Overview

The PR P/S O pneumatic O-shaped ball valve consists of two components: a PR light and small corner actuator and an 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. The O-shaped ball valve has two structural types: floating ball and fixed ball. The main features are as follows:

1. Fully open and unobstructed, it is one of the valves with the highest flow capacity.

When the valve is closed, the spherical surface and valve seat form a shearing action, which can cut off fibers and squeeze out particles, so it can control slurry media containing suspended particles or turbid liquids containing soft fibers.

3. The valve seat is made of soft plastic and always adheres tightly to the smooth spherical surface. The leakage level when the valve is closed is Class VI.

Due to its various advantages, it is widely used in various media and often serves as a shut-off valve for self-control systems; If equipped with a valve positioner, it can also be used for proportional adjustment.
