Ductile iron resilient wedge gate valves are suitable for use in potable water, sewage and fire protection systems. These valves have a rated working pressure of 25 bar with zero leakage. The waterway is clear and unobstructed.
Advantages Over Butterfly Valves
No disc in waterway to restrict flow or to increase pumping costs
Allows passage of pigging devices
Internal parts can be serviced without cutting valve out of pipeline
25bar rating provides for future pressure increases over the 16bar pressure rating typically found on most butterfly valves
Advantages Over Double-Disc Gate Valves
Zero allowable leakage
Lower torque requirements to operate valve
25 bar pressure rating compared to the 16bar rating typically found on double-disc gate valves
Epoxy-coated inside and out
Lighter total valve weight
Single-gate construction. Double-disc gate valves have multiple parts that can seize together.
Bypasses, rollers, tracks and scrapers are not needed.
Ductile Iron Construction
Triple O-Ring stem seals
Epoxy coating inside and out
Dual sealing body to bonnet gaskets
EPDM Encapsulated Ductile Iron Wedge With Polymer Guide Covers
Optional gearing (Standard on 20" and larger)
Bypass available at additional cost
Ductile Iron Construction
The ductile iron body and bonnet provide superior strength and allow a pressure rating of 25bar. The strength of ductile iron is more double that provided by gray iron. This added strength and higher pressure rating are provided in a compact, lighter design.
25 bar Pressure Rating
Our facilities are subject to periodic inspections to assure we are in compliance with their standards.
Triple O-Ring Stem Seals
Sealing the lubrication chamber is a series of O-Ring stem seals. The two O-Rings above and one below the stem thrust collar help to isolate the lubrication chamber.
Epoxy Coating Inside and Out
A fusion-bonded epoxy coating is electrostically applied to the interior and exterior of the valve body to help ensure corrosion resistance for a long service life. The coating is applied to all ferrous surfaces after the valve body is shot-blasted clean.
Thrust washers are located above and below the stem collar to reduce operating input torque and assist in trouble-free operation of the valve.
Lifting Devices, 14"-64"
All 14"-64" valves are provided with integral lifting devices, which allow the valve to be properly handled without lifting it by the operating nut.
Every valve is seat and shell tested after assembly to ensure its rated performance and that the seating mechanism is leak-tight.
Dual Sealing Body to Bonnet Gaskets
The body to bonnet gasket utilizes a unique dual sealing design which incorproates the reliabilty of a flat gasket and an integral pressure energized O-Ring seal.
EPDM Fully Encapsulated Ductile Iron Wedge With Polymer Guide Covers
Helps to ensure zero leakage with low stem torques.
Gearing allows for reduced torques and the ability to accomodate lower depths of bury.
