SA-V Reverse Valve-Pressure Switch

SA-V Reverse Valve

With a direct current geared motor, this reversing valve is designed for hydraulic Dualine systems. It can be used as either a 4/2 or a 3/2 valve.

The SA-V Differential pressure switch is employed in a dual line centralized lubrication system where the maximum pressure reaches 40Mpa. Its purpose is to regulate the directional valve or oversee the lubrication equipment/system. This is achieved by utilizing two pipe pressures to generate an electric signal, which triggers either the switching of direction or monitoring of the lubrication components. Typically, it is positioned at the end point of the two main pipelines in a terminal type two-line centralized lubrication setup.

Working Pressure:40Mpa;
Temperature Range:-20 degree to 80 Degree;
Tightening Torque:18NM;
Operation Voltage:AC110V,AC220V,DC24V;
Protection Level:IP65;

What is reverse valve?

A reverse valve is a component commonly found in the refrigeration and air conditioning systems. It is also known as a four-way valve or a reversing valve. The main function of a reverse valve is to change the direction of refrigerant flow within the system.

In cooling mode, the reverse valve directs the flow of refrigerant from the compressor to the condenser, where heat is released to the surroundings. The refrigerant then flows through the expansion valve, where it undergoes a phase change, absorbing heat from the surrounding air, and enters the evaporator. In this process, the reverse valve maintains the proper flow direction of refrigerant in order to achieve efficient cooling.

In heating mode, the reverse valve reverses the flow of refrigerant, directing it from the compressor to the evaporator. The refrigerant absorbs heat from the outside air and then flows through the expansion valve to release that heat in the indoor air through the condenser. The reverse valve plays a crucial role in the heat pump system’s ability to provide both heating and cooling functions.

Overall, the reverse valve is an essential component in refrigeration and air conditioning systems that enables them to switch between heating and cooling modes, making them versatile and efficient.

What is the different SA-V Valve and YKQ Valve?
  1. Place the YCQ differential pressure switch in a well-ventilated, dry area with clear visibility, ensuring no interference with surrounding components.
  2. Install theYCQ switch at the terminus of the main pipeline in a two-line centralized lubrication system. Position a two-line distributor behind it to prevent grease from aging, drying, and compromising sensitivity.
  3. Adjust the stroke switch wiring to the bridge center and securely fasten the screws.
