Brass Threaded Adjustable on off Pressure Independent Control Valve

PHF-DD-L series pressure independent control valve (PICV) used for balacing the piping network in HVAC system of small area where pipe size is not bigger than 50mm. The PICV combines the functions of hydraulic balancing and electrical on/off control in one unit. It controls the water flow and temperature automatically to save energy rationally and realize intelligent management by its intelligent module device. The PICV features with high control accuracy and strong antielectromagnetic interference capability, is especially suitable for the variable flow piping system with large load fluctuation.

• Heating paraffin wax pusher is used in the actuator, no noise during working.
• Adopt the design of differential pressure balancing structure of spring plus diaphragm, no water hammer and running noise.
• Both the electric valve core and balancing valve core adopt straight travel design, has higher control precision.
• Valve is automatically closed after power off by function of spring reset.
• Easy installation by thread connection.Good stability.
• Not influenced by pressure fluctuation.
• Greatly shorten the time of system commissioning and highly enhance efficiency in subsequent operation.

• Diaphragm material: EPDM.
• Stem material: stainless steel 06Cr19Ni10.
• Valve body and cover material: C3771.
• Nominal pressure (PN): 1.6MPa.
• Working medium: water, fluid temperature -10 ~ 95 deg C.
• Travel: 3mm.

DRQ electric thermal valve used for FCU temperature control as well as radiators in heating system. The control valve depends on the heating paraffin wax pusher drive the spring to reset. The electric thermal valve is normally closed when it doesn’t work. If it needs to work, the thermostat will provide a signal of opening,then the electric thermal valve will gets the power to work. when the set temperature is achieved,the thermostat will cut off the electric thermal valve’s power,then the reset spring can close the valve to stop the water which flow into the coil. So the room temperature is always maintained within the set range by PICV.
DRF-01 electric thermal valve adopts paraffin wax pusher. lt’s driven by the PTC heating without noise, with a spring reset function,the valve is closed after power off，and the position of the stroke has the indication of the opening degree. ,screw connection is simple, fast and convenient to be disassembled.
