Advantages: 1, the small flow resistance. Body within the media channel is straight, valves, flow in a straight line media, Shandong valves, flow resistance. 2, more effort when opening and closing. In contrast with the shut-off valve, because both the open or closed, the shutter movement direction are perpendicular to the flow direction of the medium. 3, height, long opening and closing times. The shutter opening and closing stroke larger drop is carried by the screw. 4, easy to produce water hammer phenomenon. The reason is that long off time. Uses gate only for fully open and fully closed media run it on various types of piping or equipment used does not allow for throttling. The valve with a hand wheel or handle, no further increase in the operator-assisted Leverage (In case Mifengbuyan, you should check to repair the sealing surface or other parts). Hand wheel, handle clockwise to close, otherwise open. Valve with a transmission mechanism should be required to product instructions for use. Features: The overall package of plastic: gate using high quality rubber within the overall outsourcing glue, valve manufacturers, Europe's leading rubber vulcanization after curing technology allows the gate to ensure accurate geometry, valves processors, and rubber and ductile Then firmly cast gate, not falling, and good elastic memory. Water Body Casting: Valve using precision casting, precision geometry makes finishing without any internal body to ensure that the valve seal.
