Product Overview

The ZPR760Y Pneumatic V-Notch Modulating Ball Valve,the valve’s core is a V-notched on the half sphere. It has a sharp cutting edge, in the process of ball rotation, there is a wiping effect between the seat, and it has a strong cutting force on the medium. The V-ball and the flow channel of the seat form a fan-shaped area, which can change the cross-sectional area of the flow channel during the rotation process to form a precise adjustment of the medium. Its sealing performance is the same as that of ordinary ball valves, so that it has two functions of Modulating and ON-OFF at the same time.

Performance Characteristics

The ZPR760Y Modulating Ball Valve with integrated valve body design,Flange connection and welding connection can be used with standards.This ball valve designed with single-seat structure.

 

The Advantages Of ZPR760Y:

1.The V-notched spool design gives this ball valve approximately equal percentage flow characteristics;
2.The V-notch has a shearing effect between the spherical surface and the seat, which can cut and scrape off fibrous media, high-viscosity media, and fluids containing
solid particles, so that they can pass through the valve smoothly;
3.The valve seat is pre-tightened by a wave spring,so that it’s always tightly fitted to the ball, achieved a good sealing performance;
4.The soft seat and metal seat can be interchanged to meet the requirements of different working conditions;
5.The precise control of small CV value can be realized by machining the spool with special V-angle;
6. With a simple structure, small size, and light weight, they are highly convenient for various applications.
