Bi-flow ball valve is manual stop valve. It has no restriction on flow direction and the operation is more convenient than other stop valves. It can be used in liquid ,suction and discharge lines in freezers and air-conditioner adjusting equipment. This valve can provide the largest flow capacity when it is totally opened and it sealed tightly when it is closed. Furthermore, the application areas of this kind of valve is extensive: -40℃~＋140℃. All the valves have the fixed hole, could be installed on panel. "Hermetically" welded construction. One quarter turn from fully open to fully closed valve, Rotation stop for fully open and fully closed .
♦ 1)Rated liquid and suction vapour capacity is based on evaporating temperature te=-10℃, liquid temperature ahead of valve t1=+25℃, and pressure drop in valve △p=0.015Mpa.
♦ 2)The Kv Value is the water flow in m3/h at a pressure drop across valve of 0.1Mpa, p=1000kg/m3.
♦ 3)The part no. which with "s" means has the access valve.
