 Features
 Light weight: the body uses advanced ductile iron, to reduce about 20% -30% lighter in weight than traditional gate valve weight, easy installation and maintenance.

 Flat gate acne: traditional gate valve is often through the washing tube after by foreign objects such as stone, wood, cement, iron, and other debris deposition on the valve end of the groove, likely to cause water leakage can not be turned off in close formation, resilient seated gate valve at the bottom of fill seal and pipes using the same flat design, not easy to cause the debris deposition in the fluid free from obstruction.

 Overall plastic packages: the gate using high quality rubber within the overall outsourcing glue, Europe's leading rubber vulcanization technology makes curing the gate to ensure accurate geometry, then solid rubber and ductile gate, not falling good elastic memory.

 Casting body: The body uses the precision casting, precise geometry of the internal body without any finish to ensure sealing of the valve.

 Embedded copper nut: Brass nuts and flexible gate embedded joints, so that the two closely integrated into one, due to water flow caused by vibration of loose or damaged phenomenon.

 Body powder epoxy coating corrosion-resistant, corrosion and rust can be spun only the valve can be used for the sewage system. Difficult to fragmentation: the past, traditional cast iron gate valves are often hit by foreign objects, collision or weight caused by the fracture phenomenon. Switch to ductile iron body, such situation could be substantially reduced.

 The three "O" ring seal: Stem three type "O" ring ring seal design, can reduce the frictional resistance when closed, significantly reducing water leakage and can not stop water construction to replace the seals.
