Valves open and close easily and quickly, saving, small fluid resistance, can often operate, simple structure, small size, light weight, can carry mud accumulation of fluid in the pipe outlet at least, low pressure, can achieve a good seal, Butterfly Valvesadjusting performance,
Valve defects
Butterfly valve valve with pressure and operating temperature range is small, poor sealing, the installation, the valve flap to stop in the closed position, open position to disc rotation should be determined with a bypass valve Butterfly valve valve, Open the bypass valve opening should be preceded.
Electric Butterfly valve valve uses the integrated structure, with features, small volume, light and pleasant, reliable performance, supporting a simple element, flow capacity, on the temperature, clean the media,Globe Valves the choice of disc plus soft seal, rubber ring, PTFE ring to reduce leakage, high temperature and pressure conditions can choose three eccentric seal body.
Pneumatic Butterfly valve valve with a new series of GT-type pneumatic actuator, double-acting and single acting spring return, gear transmission, safe, reliable, large-diameter valves with pneumatic actuator Series AW-type fork-type drive, PLUG VALVESreasonable structure, the output torque Great moment, there are double acting and single acting, dual piston gear, the output torque, small size.
Signal Butterfly valve valve for the fire signal system, control valves, normally open the occasion required, when the valve is open or closed to the specified position, the valve on the signal device can send a signal sent to the fire testing center can demonstrate valve open or closed to prevent the closure of the valve error sprinkler function.
