2Cr13 / SS431/ SS304


Product Description

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.


Standard Features

Ductile Iron Construction

25bar rating

Triple O-Ring stem seals

Epoxy coating inside and out

Thrust washers

Lifting Devices

Zero leakage

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

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.


Zero Leakage

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.


Optional Gearing

Gearing allows for reduced torques and the ability to accomodate lower depths of bury.
