Water Main Gate Valve
Know more about the soft seal gate valve
Soft seal gate valve, has overcome the normal gate valve defects which is poor sealed, elastic fatigue and easy to rust. Soft seal gate valve generates tiny deformation compensation effect from the flexible gate, to achieve a good sealing effect. The main advantages of this valve are easy to on-off, reliable sealed with good elastic memory and long using life etc.
How much do you know about gate valve seats
Fluid resistance, little erosion and corrosion occurs on sealing surface from the media.
Flat base seat----Traditional gate valve used to have foreign objects such as stone, wood, cement, paper and other debris in the notch of the valve bottom, then cause water leakage when the valve can not be close tightly. Soft seal gate valve is designed with the flat base which is in the pipe’s same level, then no more foreign objects filled in, easily to be free flowing.

The Casting Technology for Ductile Valve and Valve Body
Characteristics of ductile iron gate valves:
It is simple structure : good interchangeability and low price
Stem sealing is not easy deformation ,so avoids leakage phenomenon.
Overall support is good ,stable and solid
Use less rubber of seat ,so expansion has small impaction and easy to control torque
value at an appropriate range
Applying to two pieces of no-sells connection ,structure is simple and
convenient to be maintained
Butterfly disc owns automatic alignment function and achieved small combination of disc and seat .
Phenolic back seat is featured such as no loss ,tensile ,anti-leak ,convenient replacement etc.
For seat sealing surface and phenolic back as a whole ,it can reduce amount of deformation
