CV 200 line
CV 2x2
Control valves
NPS 1 to 6, Class 150, Class 300
Description
Control valves CV 2x2 are single-seated valves with pressure-balanced plug designed for regulation of process medium flow. This execution enables the valves to be assembled even with low-linear-force actuators. Flow
characteristics, Kvs values and leakage rates correspond to international standards.
Valves CV 2x2 are especially designed for electromechanic and pneumatic actuators of the following producers: Auma, Schiebel, Rotork and EMG - Drehmo, Auma,
Schiebel, Rotork a EMG - Drehmo, Honeywell, Fisher - Rosemount and SPA Praha.
Application
These valves have a wide range of application in heating, ventilation, power generation and chemical processing industries. Valve body can be optionally made of cast steel, cast CrMoV steel and stainless steel.
Process media
Valves series CV 2x2 are designed for regulation of flow and pressure of liquids, gases, vapours and other media compatible with material of the valve inner parts. To ensure reliable regulation, producer recommends to pipe a
strainer in front of the valve into pipeline or ensure the process medium to be without any abrasive additions or impurities.
