Electric Single Seat Globe Control Valve

Description

The electric single-seat (sleeve,double-seat) control valve is composed of ZHA(B) pneumatic multi-diaphragm actuator, P style low flow resistance straight single-seat valve, low resistance sleeve valve, and N-type low resistance double-seat valve.

Low resistance single-seat valve and sleeve valve have a simple and compact structure and high flow coefficient. Forms of bodies adopt straight single-seat and the upper guiding structure without bottom cover, and the feature is small volume, lightweight, fluent runner, and highly efficient. The connection of body and pipe adopts a male flange and male-female flange, which adapts different nominal diameters. The body is classified into ordinary temperature and middle temperature for different working temperatures. The plug type of single-seat valve is on oriented piston valve. The plug type of sleeve valve is cylinder, which is guided by inner cylinder and a certain characteristic hole on the sleeve after precision finishing. They all have accurate flow characteristics and conform to IEC standard and slope deviation requirements in national regulation. The standard filling material is PTFE, but flexible graphite can be also used according to field usage
