The Throttle Stop Valve is mainly composed of valve body, valve cover, valve flap, and valve stem. The handwheel applies a certain torque at the upper end of the valve stem. The valve stem is passed to the valve petals to move it up and down along the valve stem axis to realize the full-opening, full-closed movements and regulating traffic functions. The force applied by the hand wheel can be obsessed with the valve seat to reach the sealing state; Location, change the cross-sectional area between the valve petals and the cover of the valve seat, and achieve the purpose of regulating media flow. At the same time, the throttle stop valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the life of the valve.
An energy-saving multi-combination control valve without external energy sources, used for flow and temperature control devices for non-corrosive liquids with a maximum temperature of 350℃, as well as pressure and differential pressure control devices, and flow and pressure control devices for liquids, gases and steam.
C700 Series Single Seated Control Valve is a top-guided structure control valve, used in equipment that can achieve air opening or air closing. The fluid channel of the valve body is in an S-shaped streamlined shape, featuring low pressure drop loss, large flow rate, wide adjustable range, high accuracy of the flow characteristic curve, large guiding area of the valve core, and good vibration resistance. The control valve is equipped with a multi-spring diaphragm actuator, which features a compact structure and large output force. It can be used to control various fluids with different pressures and temperatures.
