Pneumatische Einzelsitz-Regelventil

Pneumatic Single Seat Control Valvesingle seat control valve,control valve, pneumaticHTS single seat valve is a up-leading structure control valve. The valve body which has a S-curved, minimizing losses of decompression, high capacity, widely usage range , a big square meter of disc leading, and anti-knock. This control valve used multi-spring diaphragm actuator.
