1.All connections are copper welded 2.Available full-size porting maintains unrestricted gas flow The SRV piston-style 4-way reversing valve has big capacity and new designed valve cavity. The valve body operates through cutting. The 4-way reversing valve can make the pressure drop 60% less than the corresponding products, and maintains constant flow capacity and minimizes pressure drop. With the patent designed valve core and the logical position of refrigerant flow direction ( patent No. ZL200420051226.6) reduced the inner leakage between high pressure side and low pressure side, at the same time, it can avoid the abrasion between metal components. Adoption of level principle of dismountable leading vavle designed ( patent No. ZL200420051230.2), SRV vavles will acquire the highest rate of energy and performance. Dimensions
