The dynamic flow balancing valve automatically maintains a constant water system flow over the normal operating differential pressure range, eliminating the need for on-site commissioning. The precision over-hole design keeps the flow error within ±5%. The inside and outside of the casing are coated with epoxy resin, and the detachable bolt is designed to replace the valve.
Housing material: Ductile iron, valve & spring: stainless steel
Working pressure: 350PSI, 25Bar, ANSI or BSEN flange
Size range: 2"~20"

Relying on its own high and low pressure chamber pressure changes to change the valve opening, automatic constant pressure difference, no external power source. The valve has a shutdown function, which can set the pressure difference on site and has a large controllable pressure difference range. With high pressure chamber vents, this valve is mainly used for air conditioning and heating systems.
Housing material: bronze, diaphragm: EPDM, core rod: stainless steel
Working pressure: 350PSI /25Bar, BSPT or NPT thread
Size range: 3/4"~2"

The electric two-way valve is mainly used for the switching control of the cold water and hot water of the fan coil at the end of the air conditioning system to achieve the indoor temperature comfort effect. Driven by a fully enclosed one-way hysteresis synchronous motor, spring reset, low motor power, low noise, motor speed is not affected by voltage at rated frequency. The valve body structure is divided into a normally closed two-way type and a split three-way type.
Housing material: brass, sealed: NBR, core rod: stainless steel, actuator housing: aluminium
Working pressure: 235PSI, 16Bar, BSPT or NPT thread
Size range: 1/2" to 1"

The AC synchronous hysteresis clutch motor is used. When the limit position is reached, the hysteresis clutch disengages the motor output shaft from the transmission part to protect the motor. With valve stroke adaptive function, a variety of signal control: incremental / floating point signal, voltage 0-10V, current 4-20mA. The valve body structure is divided into two-way, three-way split or merge type.
Housing material: brass, sealed: PTFE, core rod: stainless steel, actuator housing: ABS
Working pressure: 235PSI, 16Bar, BSPT or NPT thread
Size range: 1/2" to 3"

It adopts DC brushless motor, high efficiency, low noise and low power consumption. The current of the motor is detected to achieve overload protection, thereby simplifying the mechanical structure. It has valve stroke adaptive function and fault self-diagnosis function. Under the condition of receiving instrument and computer output various control signals, temperature and pressure adjustment can be realized, and parameters such as flow rate and liquid level can be controlled. The valve body structure is divided into two-way, three-way split or merge type.
Housing material: cast iron, sealed: PTFE, core rod: stainless steel, actuator housing: cast aluminum
Working pressure: 235PSI, 16Bar / ANSI or BSEN flange
Size range: 11/2" to 6"

For the structure of the clip-on-ear type, the valve seat and the valve body are combined with a recessed recessed design, and the housing is sprayed with epoxy resin.
