The importance of selecting the right valve
Valves are more than a device for turning on and off flow. Designs must keep in step with industrial progress and the ever-increasing number of fluids.
The development in valve design has given engineers a variety of valve types to choose from. It’s a case of carefully matching up the service requirements with the design characteristics of the valve, taking into consideration the medium to be handled, the working pressure, temperature, cost and installation.
Our extensively trained sales engineers are dedicated to helping you select the right valve for your application.

Our Valve Products
Globe valves have a flow path that changes direction, causing increased resistance and pressure drop, making them suitable for throttling flow. Their seating is parallel to the flow line, unlike gate valves, and contact between seat and disc ends when flow starts.
They feature shorter disc travel, requiring fewer turns to operate, saving time and reducing wear on parts. While not recommended for applications where flow resistance is an issue, globe valves are ideal for frequent operation and throttling purposes.

Check Valves
Check valves to prevent backflow and protect downstream equipment. Swing check valves are suitable for both horizontal and vertical pipelines. Similar to globe valves in flow restriction, work best in horizontal pipelines with vertical bonnets. Cast iron ball check valves, known for their non-clog and low-maintenance design, are ideal for sewerage and general water control, ensuring reliable shut-off in various orientations without mechanical aids.
Gate Valves
Gate valves are mainly used in industrial piping to either fully open or completely shut off flow, making them unsuitable for regulating flow or frequent use. Their design allows for minimal flow resistance when open, but their perpendicular seating to the flow line can lead to seating surface damage with frequent operation.
Ball Valves
Ball valves have a spherical disc, which is the part of the valve that controls the flow through it. The sphere has a hole, or port, through the middle so that when the port is in line with both ends of the valve, flow will occur. Ball valves are used extensively in industrial applications because they are very versatile and easy to repair and operate.
Butterfly Valves
Butterfly valves, named for their disc’s wing-like rotation perpendicular to the flow, feature a resilient liner for bubble-tight sealing with low torque. These lightweight valves, with elastomer seats and seals, are versatile for full or closed positions and some throttling applications.
Knife Gate Valves
Knife gate valves are used to slice through sludge or sewerage. It is a great valve design that is distinguished from the standard design by the use of a simple metal plate for the gate and the absence of a bonnet, which is also called a slide valve.
Plug Valves
Plug valves are cylindrical or conically-tapered plugs that can be rotated inside the valve body to control flow through the valve. The plugs in plug valves have one or more hollow passageways going sideways through the plug so that fluid can flow through the plug when the valve is open. Plug valves are simple and often economical.
Needle Valves
A needle valve has a relatively small orifice with a long tapered seat and a needle-shaped plunger on the end of a screw, which exactly fits this seat. As the screw is turned and the plunger is retracted, flow between the seat and the plunger is possible.
Steam Traps
A steam trap is a device used to discharge condensate and noncondensable gases with a negligible consumption or loss of live steam. Most steam traps are nothing more than automatic valves. They open, close or modulate automatically. Others, like venturi traps, are based on turbulent 2-phase flows to obstruct the steam flow.
Pressure Reducers
A pressure reducer is a valve designed to limit the flow in a pipeline to a specific pressure, ensuring the safety of equipment and maintaining the flow at a manageable level. In systems where steam, air, water, gas, or chemicals are utilised, devices like boilers, pumps, and compressors are employed to pressurise the system.
Penstocks
Safety/Relief Valves
Safety relief valves are designed to automatically discharge gas, vapour or liquid from any pressure-containing system, preventing a predetermined safe pressure from being exceeded to protect both plant and personnel. Protecting the effects of exceeding safe pressure levels in an unprotected pressure vessel or system can have.
Y-Strainers
Gauge Cocks
The T73 Gauge Cocks are designed for connecting pressure gauges to boiler or syphon and also suitable for connecting vacuum gauges.
