Ductile Iron RS Rising Stem Resilient Seated Gate Valve For Water Pipeline Use
Product Introduction:
A gate valve is like a gate, with the movement direction perpendicular to the direction of the fluid, and gate valve can only be fully open and closed, not adjusted or throttled.
Gate valve with following working principle: turn the hand wheel to open and close the valve plate connected to the stem by the hand wheel and stem thread advance, back, lift or drop, very easy operation.
Valve gate with two sealing surface, resilient seated gate valve sealing surface is made into a gate that can produce slight deformation to improve its processability and compensate for the deviation of the sealing surface angle during the processing. This is the reason why we we call it as a resilient seated gate valve.

Product features:
- High quality rubber is adopted for the internal and external encapsulation of valve, and the connection between rubber and valve is reliable and not easy to fall off;
- As three "O"-shaped rings are designed on valve rod, the friction resistance of switch can be reduced and water leakage can be decreased significantly;
- Corrosion resistance.
Product advantages:
1. Simple structure: the rising stem gate valve is composed of a simple body, gate plate, stem, etc., which is easy to install and maintain.
2. Good sealing performance: the sealing performance between the gate and valve seat is good, which can effectively prevent medium leakage.
3. Long service life: the material and structural design used in the rising stem gate valve give it a longer service life.
