I. Overview

The PR P/S OG pneumatic hard seal O-shaped ball valve consists of two components: a PR light and small corner actuator and a hard seal 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. It is the sealing of the metal valve seat against the surface of the metal sphere; Therefore, it not only has the characteristics of low resistance and good cutting performance shared by O-shaped ball valves, but also has the following advantages:

When the valve is closed, the metal valve seat and the metal spherical surface form a shearing action, which can cut off fibers, squeeze out particles, and not be afraid of wear from hard particles. Therefore, it can control the packing medium containing hard particles, such as cement mortar, mineral mortar, etc.

2. It can work at higher temperatures and has a leakage level of up to level VI.

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