GV120 Top Guided Single Seated Control Valves

Product Details:


11-1


Performance Characteristics   

1, Top oriented action and low flow resistance design

2, Especially suitable for occasions with small pressure difference and can be applied to non-cavitation liquid and gas with noise in the specified range

3, Small size, light weight, simple flow with big capacity in the valve body

4, Especially suitable for controlling medium flow with suspended solids and granular. Avoid coking, bonding, blocking,with good control of high viscosity liquids and slurries

5, By using special materials (carbide, ceramics etc.) for valve trim and various surface treatment technology (nitriding, hardening treatment), valve can be used for a variety of harsh conditions

6, Plug with precise design makes valve flow to be almost perfect equal percent and linear, so that the valve has a high precision, high performance controlling function


Product Advantage   

1, High sealing performance, cost-effective

2, Non-pipeline connection can be used for actuator and positioner, with high speed installation, high reliability and small installation space. Can be equipped with multi-spring pneumatic diaphragm actuator or electric mechanism

3, Removal and installation of valve body and trim is simple and this makes future detection and maintenance easier

4, The parts commonality are improved and the product cost of manufacturing and maintenance are reduced due to the modular design of the valve trim.
