The positioner is the performance-critical link between the control system demand signal and the actual valve position — a poorly selected or badly calibrated positioner can destabilise a control loop…
The steam system valves protecting a power generation turbine operate in the most demanding conditions of any valve application — high temperature, high pressure, fast cycling, and zero tolerance for…
HVAC valve selection is deceptively technical — the choice between two-way and three-way configurations, the distinction between pressure-dependent and pressure-independent valves, and the correct authority ratio all have major consequences…
The inherent flow characteristic of a control valve — linear, equal percentage, or quick opening — describes how flow changes with valve opening in a test rig with constant pressure…
Quick Summary: Severe service control valves are purpose-engineered for applications where standard valves fail within months — high pressure drop, cavitation, flashing, erosion, and aerodynamic noise demand specialised trim design,…
Valve commissioning — the process of installing, checking, testing, and handing over a valve system for operation — is where months of careful specification and procurement work either pays off…
HVAC (Heating, Ventilation and Air Conditioning) systems in commercial buildings, hospitals, data centres, and industrial facilities consume enormous quantities of energy and require precise flow control across heating and cooling…
The Industrial Internet of Things has arrived in the valve industry, and it is transforming how operators manage, maintain, and optimise their flow control assets. Smart valve positioners, wireless transmitters,…
Whether you’re specifying a valve for a new greenfield facility or troubleshooting a persistent problem in a legacy system, understanding how valves interact with process fluids under dynamic conditions is…
A valve positioner is not just a convenience accessory — it is the component that closes the position feedback loop on a control valve, eliminating the effect of friction, unbalanced…
