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.

Repair and Recondition Services

Our company offers comprehensive reconditioning and calibration services for valves, including the provision of boiler valves and gauge glass spares. Our specialist services enable us to recondition, test, and return valves in an ‘as new’ condition, offering a cost-effective alternative to purchasing new valves. 

We pride ourselves on delivering prompt and efficient service, aiming to minimise disruption to your business operations. For any calibration, repair, or reconditioning needs for your valve systems, feel free to contact our expert team, who are ready to provide the necessary service.

Valves for Industry

Our valve service business supports a range of industries with specialised valve solutions. In the power industry, we provide essential valves for energy generation and distribution. The water industry benefits from our valves for effective water management and distribution.

For the mining industry, we offer robust valves for safe and efficient mineral extraction. In the oil and gas sector, our specialised valves ensure safety and control in resource extraction and processing. The hydrocarbon industry relies on our valves for handling and processing hydrocarbons.

Additionally, we cater to general industries with a diverse range of valves supporting various applications, ensuring operational efficiency and safety across sectors.

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 provide an efficient and economical means of flow control in all open channels, dam walls or similar applications. They are the correct choice for controlling flow in irrigation channels, water and sewerage treatment plants and flood control systems.

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 are designed to stop particles of dirt and pipe muck from passing through a pipeline and damaging sensitive equipment with minimum pressure drop.

Gauge Cocks

The T73 Gauge Cocks are designed for connecting pressure gauges to boiler or syphon and also suitable for connecting vacuum gauges.

Blow Down Valves

The Dreadnought Fig BDV Blow Down Valve is suitable for attachment to all types of boilers. These blowdown valves are fitted with a stainless steel ball and reinforced PTFE seats. They have a quick quarter turn action to open & close and are full bore. Valve keys are supplied with the valve as a standard.
