Low resistance backflow preventer product performance and the scope of application is based on the principle of hydraulic control, has a compact structure, reliable isolation, small head loss, small size, light weight, easy installation and maintenance and so on. Mainly used in water supply system, water system and municipal pipeline system, can prevent and isolate unclean water backflow pollution of drinking water.

Electric control valve is a hydraulically operated valve with solenoid valve as pilot valve. Commonly used in water supply and drainage and industrial systems in the automatic control. According to the electric signal remote control to open and close the pipeline road system, to realize remote operation. Valve closing speed is adjustable, smooth closing without pressure fluctuation. Electric control valve structure is novel, customized on demand, good sealing effect, low resistance, high flow, good sensitivity, long service life and so on. Manual control device is added to this valve, when power failure or circuit failure, this valve can still open or close.

A control valve, also known as a control valve, accepts the control signal output from the regulating control unit and operates to change the fluid flow with the help of power. Control valves are generally composed of actuators and valves. Control valves are suitable for air, water, steam, various corrosive media, slurry, oil and other media, widely used in electric power, chemical industry, metallurgy, environmental protection, water treatment, light industry, building materials and other industrial automation system fields.

Slow closing check valve consists of main valve, check valve, needle valve, ball valve, micro filter and pressure meter to form a hydraulic control receiver system. Utilizing hydraulic automatic operation, it can make the main valve get opening or closing speed. Preventing the generation of water strike of water clock, in order to achieve slow closing muffling. This product utilizes hydraulic self-control, without other devices and energy, easy maintenance, smooth opening and slow closing. It is mainly used in building, living area and other water supply pipe network system and city water supply project.

Angle type adjustment valve is composed of direct stroke electronic electric actuator and angle type adjustment valve body. Electronic electric angle control valve has the characteristics of sensitive action, simple connection, large flow, small volume, high adjustment accuracy. The valve body is right-angle shaped, the spool is a single-guide structure, the valve body has a simple flow path and low resistance. Especially suitable for high viscosity, containing suspended and granular media fluid regulation, can avoid coking, bonding, clogging.

Flow control valve by the main valve, flow control valve, needle valve, pilot valve, ball valve, micro-filter and pressure meter composed of hydraulic control receiver system, the use of hydraulic automatic operation, control and adjust the main valve opening, so that the flow through the main valve to maintain a constant. Flow control valve using hydraulic self-control, without other devices and energy, easy maintenance, stable flow control. Flow control valves are widely used in high-rise buildings, living quarters and other water supply network systems and urban water supply projects.
