Ductile Iron NRS Resilient Seated Gate Valve For Water Pipeline Use
Product introduction:
Gate valve is a valve 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, It is
widely used in petrochemical, pharmaceutical, electric power and
other industries
Resilient seat sealed gate valve is a type of soft sealed gate
valve, which is an industrial valve of elastic gate valve. Its
opening and closing component is the gate, and the direction of the
gate's movement is perpendicular to the direction of the fluid. The
gate valve can only be fully open and fully closed, and cannot be
adjusted or throttled.
Soft sealed gate valve is a replacement product of traditional gate
valve, which utilizes the compensation effect of elastic gate plate
to produce slight deformation and achieve good sealing effect. This
valve has significant advantages such as lightweight switch,
reliable sealing, good elastic memory, and long service life. It
can be widely used in fluid pipelines such as tap water, sewage,
construction, food, electricity, medicine, metallurgy, textile,
energy systems, etc.

Product features:
1. Resilient seated gate valve with flat bottomed valve seat, no
accumulation of dirt, making the sealing more reliable.
2. Resilient seated gate valve disc is wrapped in nitrile rubber as
a whole, and the valve internals are made of corrosion-resistant
and rust resistant steel and copper alloy materials, which can be
used in sewage systems to adapt to harsh working environments.
3. Resilient seated gate valve with small volume and light weight,
making it easy to install and maintain.
4. Resilient seated gate valve stem is sealed with three O-ring
seals, greatly reducing friction resistance during opening and
closing. The switch is lightweight and leak free.
