DN200 Flanged Gate Valve With Handwheel 8In Non Rising Stem Resilient Seated

Gate valve controls the media's flow by lifting the gate (open) and lowering the gate (closed). A gate valve's distinct feature is the straight-through unobstructed passageway, which induces minimal pressure loss over the valve. The unobstructed bore of a gate valve also allows for a pig's passage in cleaning pipe procedures, unlike butterfly valves. Gate valves are available in many options, including various sizes, materials, temperature and pressure ratings, and gate and bonnet designs.

• Triple "O" seal: The valve stem adopts triple O-shaped ring seal, which is easy to open and close without water leakage.
• Flat bottom valve seat: The bottom of the valve body is designed to be flat, which avoids debris and sludge at the bottom of the valve, and the fluid channel is unobstructed.
• Overall rubber coating: The valve body adopts overall rubber coating to improve sealing and service life.
• Light weight: Made of ductile iron, it is lighter than traditional gate valves.
• Corrosion resistance: The inner wall is coated with non-toxic epoxy resin, which is suitable for raw drinking or sewage systems.

• The installation position, height and inlet and outlet direction must meet the design requirements, and the connection should be firm and tight.
• Handle of all kinds of manual valves installed on the insulation pipeline shall not be downward.
• The valve must be inspected before installation, and the nameplate of the valve should comply with the current national standard GB 12220.
• Handwheel, handle and transmission mechanism are not allowed to be used for lifting, and collision is strictly prohibited.
• Gate valves with driving mechanism should be installed according to the instructions of the product.
