Pressure Reducing Valves
Linder is the official authorised distributor for MATICA valves. Pressure reducing valves hold downstream pressure precisely constant regardless of inlet fluctuation or changing demand. Across steam, water, air, acids, alkalis and condensate, they deliver process safety, efficiency and equipment protection.

What Does a Pressure Reducing Valve Do?
A pressure reducing valve takes a high, variable inlet pressure and converts it into a constant, pre-set downstream pressure. The critical word is "constant": the outlet stays put whether the inlet fluctuates or demand rises and falls.
That solves three problems at once:
- Equipment protection: a heat exchanger, gasket or instrument fed above its design pressure either fails immediately or has its life cut short.
- Process stability: in steam, pressure is temperature; fluctuating pressure means fluctuating product quality.
- Energy and consumption: a system running at higher pressure than it needs is a continuous, unnoticed waste.
Where Are They Used?
Steam Lines
High-pressure steam leaving the boiler is stepped down as it travels from the distribution main to the consumer. On steam a reducing valve is also a temperature control element; the saturated steam table cannot be ignored during selection.
Water and Process Liquids
Where mains or pump pressure is high, they protect fittings, filters and instruments, and reduce the noise and vibration that high pressure creates.
Compressed Air and Gases
They bring compressor line pressure down to what the point of use actually needs. In an air system, 1 bar of unnecessary pressure is a measurable energy cost.
Aggressive Media
In acid, alkali and condensate service the choice of body and trim material becomes more critical than the pressure figure itself.
MATICA VR Series Pressure Reducing Valves
All three series are supplied directly through Linder as the official authorised distributor.
- MATICA VR100 — pressure reducing series for general industrial duty.
- MATICA VR200 — series covering different connection and capacity requirements.
- MATICA VR300 — series engineered for demanding process conditions.
Sizing: Going Bigger Is Not the Answer
The most common mistake is selecting the valve to match line diameter. The correct method is to size it on flow rate and differential pressure. An oversized reducing valve runs unstable at low flow: downstream pressure hunts, the trim wears early and the line becomes noisy.
| Data required | Why |
|---|---|
| Inlet pressure (min–max) | Pressure ratio and number of stages |
| Required outlet pressure | Spring/pilot range selection |
| Flow rate (min–normal–max) | Valve size — not diameter |
| Medium and temperature | Body and trim material |
Installation Recommendations
Standard practice is a strainer upstream, adequate straight pipe downstream and a safety valve after the reducing station: when the reducing valve fails, the safety valve is the only thing protecting the downstream line.
