【Evaporation/Condensation Pressure and Temp Test&High/Low-pressure Temperature Test HVAC Manifold】The HVAC gauges could operate dual pressure and temperature test to help you determine refrigeration capacity of refrigeration system. The lower the pressure and temperature of the evaporation(Ev)/condensation(Co) are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do. It also could test the temperature of the refrigerant in the high/low-pressure pipes..
【Superheat and Subcooling Test&Pressure Leak Test】When refrigerant type is set and temperature clamps are connected to air conditioning pipes, HVAC gauges automatically read the degree of Superheat(SH) and Subcooling(SC). The higher the degree of superheat, the smaller the opening of the expansion valve (the refrigerant filling is less) can be determined. Calculate the pressure difference between the initial test pressure and the second test pressure to determine if the refrigerant is leaking..
【Vacuum Pumping & Refrigerant Filling & Built-in 89 kinds of Refrigerant Database HVAC Manifold】Digital manifold gauge set can connect refrigeration equipment and vacuum pump for vacuum pumping operation. Vacuum pumping can make it easier to fill the refrigera....
Water Filter Float Ball Valve 1/4 Inch Adjustable Float Valve Plastic Water Tank Float Valves for Ponds, Water Pump, Water Trough, Aquariums, Aquaculture, Water Tank, Reservoir (4)
Size and material: you can connect float valves to the 1/ 4 inch supply tube, you can install an appropriate number of water float valves according to the size of the water tank to meet your needs in different situations.
The ball of the water float valve is made of PE material, the other parts are made of POM material, low temperature resistance and corrosion resistance, durable and non-toxic, can serve you for a long time.
Adjustable design: the plastic water tank float valves come with adjustable arms, when the water level of the water tank is low, the gate of the float valve opens to ensure that water can enter, when the water level rises, the ball of the water float valve and the adjustable arm will form a flat angle and close in this state, realizing the automatic adjustment of high water level and low water level.
Wide applications: the adjustable sink float valve can be applied for ponds, small water tanks, toilet storage tanks, household water purifiers, pools, aquariums, aquaculture, reservoirs, industrial and large water tanks, etc., if needed, you can choose to use multiple float valves at the same time, so that water can be input faster.
Easy to operate: the angle of the valve ball is adjustable, you can flexibly set according to the requir....
