KVSR KVSRy pneumatic O-type regulating (cut-off) ball valve is a rotary control valve with a 90 ° angle. It consists of a pneumatic piston actuator and an O-shaped ball valve, with a cylindrical through-hole ball valve core. KVDR KVSR is a soft sealed ball valve, while KVDRy KVSRy is a hard sealed ball valve. Pneumatic piston actuators are divided into single acting and double acting types. The valve body is made of straight through casting, and the spherical surface is processed and hardened by special technology to make its surface smooth and wear-resistant. It has good performance such as long service life, compact structure, reliable action, high flow capacity, low flow resistance coefficient, and easy installation. It is widely used in industries such as papermaking, petrochemicals, metallurgy, water treatment, and food, and is particularly suitable for process control with high viscosity and fiber media.
