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.
Soft seal gate valve, the substitute product of traditional gate
valve, can achieve sound sealing performance by the compensation
function of micro deformation of elastic gate valve. As it is
superior for its light and flexible switch, reliable sealing,
excellent elastic memory and long service life, the valve can be
widely applied to fluid pipeline, including tap water, polluted
water, buildings, food, electricity, medicine, metallurgy and light
textile, as adjustment and closure equipment.

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.
4. Excellent truncation performance: the rising stem gate valve can
completely cut off the flow of the medium in the closed state, and
has good cutting performance.
5. Wide applicability: rising stem gate valves are suitable for
various media, including liquids, gases, and powders.
