Most effective filtration provided by the dry surface.
Good filtration of fibreglass network controlled by the process.
Safe working pressure of:3.5mpa.
The delayed flow demonstrates its performance free of disturbance.
Soluble to such contaminants as water and acid
Both odf and sae type connectors available
Suitable for r12, r22, r134a and r502 refrigerants
Solenoid valve
Specifications
sv series solenoid valve is a kind of normally closed, two-channel trait , acted as a pilot valve, it usually is applied in the liquid refrigerant or exhausting air and water or compressing air, with the features as below:
nut system with o ring ensures watertight performance and strengthens the watertight performance of the coil.
the elaborately designed coil winding conforms to ce161-lstandard and able to remain functioning under extreme conditions.
the coil winding can be fitted with plug-in connector, which is configured with three wires and can be connected very easily.
electromagnetic coil employ moisture-proof resin windings, which possesses water-proof and shock resistant characteristics.
there is no need to shut systematic pipe line when replacing the electromagnetic coils.
the valve can evaporate normally, be opening or closing, under the condition that there is no pressure differential of the refrigerant media.
24v, 110v, 220v and 380v electromagnetic coil are available and please inform us of that when placing order.
Differential pressure control
Specifications
Differential pressure for pressure control is adjustable.
Suitable for the control of condensing water-cut.
For use with fluorinated refrigerants as well as with air and liquid.(allowable fluid temp - 45 ~+110f¦)
Novel micro-switch ensures reliables switching.
Agile mounting bracket is suitable for different occasions.
Being loaded with high pressure, the pressure control can be used as oil pressure protector of screw compressor units.
Differential pressure control without time delay device.
Please make it clear to the manufacturer when the order is placed if the system adopts the media corrosive to phosphor and bronze, suitable models will be recommended for that system
Expansion valve
Specifications
Heat expansion valve is a key component of refrigerating system.It is usually mounted between the liquid accumulator and evaporator to allow liquid of high temperature and pressure to become moisturized steam of low temperature and pressure after being throtted.Then the refrigeration is achieved througn the heat being absorbed by the refrigerant in evaporator.Heat expansion valve control the flow of the valve through regulating the overheating degree at the end of evaporator in order to avoid inadequate use of the surface area of evaporator and prevent sinter being produced on the bottom of evaporator. Overheating degree regulation: remove the seal nut and turn the regulating leveer one round counterclockwise, and then the overheating temperature decrease by
the factory set over heat temperature is 3.5f¦ and the static overheating degree can be ranged 2f¦~8f¦ basic features
the consistent overheating degree allows stable operations of the system;
applicable to the needs of refrigeration and air-conditioning;
temperature of evaporation is ranged-40 + 10
applicable to the media of r12, r22 and r134a; note:special requirements should be informed when placing order.
Stop valve
Bm stop valve is a kind of manual stop valve, applied to the liquid, air section and heated air in the lines of refrigeration units.
Specifications
Available with all fluorinate refrigerants.
The valve could be fully closed with minimum torque exerted on teflon valve board.
The three stainless steel shims can effectively prevent leaking during the entire life cycle of the valve.
The hidden valve cover helps prevent moisture penetration.
Liquid temperature range:-40~+120f¦;
Max. Working pressure: 3.5mpa.
Note: kv is the water flux when the pressure decreases to 1 bar and ¬-=1000kg/m3.Unit:m3/h
Moisture indicator
Sg-series sight glass(moisture indicator) is a kind of element which shows the moisture and the flow of refrigerant.
The content of refrigerant in the line of the system;
The content of water in the refrigerant;
Indicates the oil level of compressor crooked.
Sg-series have indicator paper whose color changes can indicate the content of water in the refrigerant;
The glasses and the fªofª ring can make sure there is no leak of the refrigerant;
Max. Working pressure: 35bar (500psig);
The temperature of the medium: -50f¦ f+ +110f¦;
The content of water is low, the color will change blue while high it will change pink which shows that filter dryer in the system needs to be changed.
