  • Shut-off Stop Valve

    Shut-off Stop Valve

    1. Ammonia refrigeration valve welding stop valve cold storage installation steel pipe valve welding valve
    2. The stop valve for refrigeration is made of cast steel, integrated and good quality.
    3. The shut-off valve is also called a cut-off door. It is the most widely used type of valve. It is popular because the friction between the sealing surfaces is small during the opening and closing process, relatively durable, not large opening height, easy manufacturing, the convenient maintenance. It is not only suitable for medium and low pressure, but also for high pressure.

  • Throttle Valve

    Throttle Valve

    The REG-SA and REG-SB are angle and straight-through manual regulators that act as normal shut-off valves in the closed position. Valves are available in two different versions, REG-SA and REG-SB. REG-SA is mainly used for expansion/throttle lines (type A spool); REG-SB is mainly used for flow regulation of liquid lines (type B valves) core). The valve meets the stringent quality requirements for refrigeration installations specified by the International Classification Association and provides good flow and linear adjustment. REG-SA and REG-SB are equipped with square hole bonnets and have a back seal function to replace the stuffing box of the valve stem during system operation (in the presence of pressure).

  • Ammonia Pump

    Ammonia Pump

    The shielding pump is a coaxial combination of a shielded motor and a centrifugal pump. It is a completely leak-free sealing device that does not require any mechanical seal packing. The medium to be transported is guaranteed to be leak-free. It has the characteristics of advanced design, compact structure, high efficiency, energy saving, low noise, simple installation and convenient use. This product fundamentally solves the environmental damage caused by highly toxic liquid leakage and explosive liquids.
    Shielding pump is most suitable for conveying flammable, explosive, corrosive, toxic, valuable and volatile liquids with low particle flow and high lift. It can be widely used in refrigeration, chemical, petroleum and food processing industries.

  • Bypass valve

    Bypass valve

    1. This bypass valve is suitable for R717, R12, R22 and other refrigerants. It is commonly used in the ammonia pump outlet pipe. When the cooling interval is reduced, the excess ammonia is bypassed, so that the warehouse can It cools normally and can protect the ammonia pump. In addition, it can also be used as a decompression bypass in the intercooler and cold storage evaporator frosting circuits.
    2. This is an automatic bypass valve with a diameter of 32 mm and an adjustable pressure difference of 1.8-3.2 bar for low-pressure bypass. The set pressure is achieved by changing the stroke of the ram. If the spring is replaced, it can also be used as an automatic bypass valve for medium or high pressure.

  • Ammonia pump control box

    Ammonia pump control box

    1. The ammonia pump control box is a centralized control box for the automatic control components of the cold storage ammonia pump circuit. The ammonia pump control box cooperates with the self-control components such as the liquid level meter, the electromagnetic valve and the differential pressure relay, and can automatically supply the ammonia liquid to the ammonia storage tank, which can automatically ensure the normal start and operation of the ammonia pump. The ammonia pump control box automatically alarms the dangerous operating conditions of the ammonia pump and compressor.
    2. The ammonia pump control box is simple in structure, safe and reliable, and easy to maintain. It is suitable for automatic control of cold storage.

  • Plate level gauge

    Plate level gauge

    The plate level gauge is suitable for directly indicating the measurement of the liquid level in various towers, tanks, tanks, tanks and the like. A safety steel ball is installed in the upper and lower valves of the instrument. When the glass is accidentally damaged, the steel ball can automatically close the liquid flow channel under the pressure of the container to prevent the liquid level from continuing to flow out. Install a liquid level gauge in a low-temperature position such as a low-pressure circulating drum, and use it with a fuel pack. The plate level gauge is mainly used for liquid level measurement and can be used in industrial, cold storage, boiler and so on.
