Description

This kind of gate valves are designed well in every detail. The wedge is fully vulcanized with approved EPDM rubber . It features an outstanding durability due to the ability of the rubber to regain its original shape, the double bonding vulcanization process and the sturdy wedge design. The high strength stem and the thorough corrosion protection safeguard the unmatched reliability. The outside diameters of the spigots are the same as those of cast iron pipes; (other sizes on request).

Features:

? Wedge inside and outside fully rubber vulcanised, with special guiding rails to minimize friction.

? Solid flexible wedge nut from pure brass material. Homologated for drinking water and certified according to EN 1074.

? The watertightness for the spindle is obtained with three O-ringsstemseals.?

? Bonnet bolts in Galvanized carbon steel, sealed with hot melt to prevent corrosion. other material upon request.

? Coating - Electrostatically applied WRAS Approved fusion bonded epoxy coating.?Technical information

? Manual operation by handwheel, head square cap, extension spindle (underground installation).

? Spigot type gate valve to connect directly with socket ductile iron pipes.?

? Clockwise closing (CWC) as standard, anti-closewise closinguponrequest.?

? Corrosionresisitantstemssealing andlowmaintenance.?

? Body and bonnet high quality epoxy powder coated (fusion bonded), coating thickness (min.250 microns).

? O-ring bonnet gasket wraps each bolt to prevent corrosion.

Technical Data

Attention:

1.The valve is installed independent of the flow direction of the medium.

2.?After the valve is assembled, the thread of the bolt/stem shall be greased to prevent corrosion and facilitate subsequent disassembly.

3.?Do not use the valve for pipe pressure regulation, gate valves generally play the role of a switch, to achieve a good adjustment effect, it is recommended to choose a professional regulating valve, water erosion will affect the service life of the valve disc.

4.?Do not use valves with EDPM for gaseous fluids.

Installation instructions

1.?Notice of water stop shall be issued before construction.

2.?The water in the road should be avoided in the front row of construction.

3.?Electricity for construction must be guaranteed.

4.?It is strictly prohibited to use hand wheel, handle and transmission mechanism for hoisting and collision is strictly prohibited.

5.?Lubricate the valve at least once a month if it is in frequent use.
