Stainless Steel Bonnet Bolts Lightweight Resilient Seated Gate Valve
Resilient Seated Gate Valve Design features:
Spindle’s gaskets O-ring - “DRY THREAD” - replaceable under pressure.
Stainless steel spindle with rolled thread and bearing.
Total sufrace rubbered wedge with replaceable spindle nut.
Resilient seated gate valve to EN 1074-1 and 2 / EN 1171, with WRAS approved EPDM
rubber parts.
The valve gate or closure member is typically in the form of a wedge made of cast iron material
so as to be sufficiently rugged so as to be suitable for high pressure and high flow applications.
In a resilient seat gate valve, the outer surface of the valve wedge is coated with an elastomeric
material so as to offer a bubble-tight seal even at elevated operating pressures.
The valve wedge is operated by turning a threaded stem so as to advance or retract the valve
wedge within the waterway of the valve housing.
Upon valve closure, the resilient material on the edge forms a bubble-tight seal with the internal
surface of the valve body. Dirt or other contamination in the valve operating system can lead to
incomplete sealing of the wedge or other malfunction.
A. Stem sealing
Three independent stem seals offering triple safety:
• A NBR wiper ring protects against dirt from outside.
• A polyamid bearing with 4 NBR O-rings protects against galvanic corrosion.
• An EPDM rubber manchette sealing acts as the main hydraulic seal to the flow.
B. Body/bonnet connection
The unique assembly of the valve body and bonnet ensures a durable tightness:
• A round rubber bonnet gasket fits into a recess in the valve bonnet preventing it
from being blown out by pressure surges.
• The stainless steel bonnet bolts are countersunk in the valve bonnet, encircled
by the bonnet gasket and sealed with hot melt. Thus there is no risk of corrosion
as the bolts are not exposed to the medium or soil.

Resilient Seated Gate Valve FEATURES
⊙ Shot-blasting
protective surface finished by shot-blasting and the surface is smooth and neatness.
⊙ Flatting seat
Smooth continuous bore way without seating recess, it is not easy to get impurity pilled up.
Making the liquid straightway.
⊙ Treating with rubber
Both inner and outer are coated with advanced knowledge of rubber vulcanization then making
sure of the elasticity of rubber ,and make sure the exact geometry dimension. Rubber and ductile
cast iron valve hand together hardly. This can avoid fall-off due to long-term use.
⊙ Anti- corrosion
Both inner and outer are coated with non-toxic powder epoxy resin to strengthen the capacity of Corrosion resisting and raise the quality
of water supply.
⊙ Ruggedization
The older ductile iron valve is easy to rupture after being impacted by nonego. It can stop
rupture depend on the good mechanics capability of ductile iron .
Applications : This valve widely applied in the liquid pipes for opening or closing fixing in such
water, sewage disposal, electric power, energetics pipe , chemical, shipping, energy sources etc.
