Controls

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Our portfolio of control valves fall into three broad classes based on the severity of the application they serve: general service; semi-severe and severe service. Our portfolio includes several proven technology platforms, including BTG, ABJ®, DRAG®, Zikesch, IMI Bopp & Reuther and the valve technology acquired from Sulzer® Ltd. These technologies allow customers to balance the ease of installation against noise abatement, reliability and control. Our portfolio of pneumatic, hydraulic and electric actuators, also enhances control functions. ​

We leverage experience gleaned from an installed base of over 250,000 valves supporting multiple industries and operating profiles, which makes our engineering expertise unrivalled and uniquely capable of providing finely tuned valve solutions derived from system-wide process insight.

Attemperator
Ensuring power plants operate economically with daily cycling or reduced loads requires reliable superheat and reheat stages to optimise the heat recovery steam generators and ensure the steam is nea

Boiler Level Control
The task of any steam boiler is to provide the correct amount of high quality steam: safely; efficiently; and at the correct pressure. A certain area of water surface is required in a boiler from

Bypass Valves
Bypass valves are designed to divert steam from one part of the system (such as power generation or process steam such as paper and pulp production) to a reheat or exhaust piping to safeguard equipmen

Control
Control valves are designed to provide staged flow and pressure control through the movement of the plug (or disc) to provide a smooth regulated flow in the pipeline.Available in several technologies,

Desuperheating
Steam condition is critical to ensure steam is near saturation. If it is too hot, it will cause equipment damage and if it is too cold it will leave water in the pipework and valves which can lead to

Globe
A globe valve is for regulating flow in a pipeline, consisting of a movable disk (also called a plug) element and a stationary ring seat typically in a spherical body. The inlet and outlet of the body

HIPPS
HIPPS (also referred to as HIPS) systems are a series of components, specifically engineered to isolate the source of dangerous high pressure instead of relieving the excess flow, in the case of an ov

Safety Valves
Safety valves are designed to prevent inadmissible overpressure in pipe systems, pressure vessels and boilers in order to avoid danger to people, plant and the environment.
