Regulators

Analyser Range

From gas cylinder regulators to ATEX certified (94/9/EC) heated regulators, our versatile range of instrumentation regulators have endured extensive cycle tests and include design features that make us the market leaders in this sector.

High Pressure Range

An extensive range of piston sensed regulators control pressures up to 690bar (10,000psi) via a range of precision machined sensors. The range covers 1/4” to 1” connections, with designs for both gas and hydraulic service and flow capacities from Cv 0.1 to 7.0.

Process Range

The DM and UV range of regulators are manufactured in deep drawn stainless steel to offer light weight valves covering sizes from 1/2” to 6” – controlling pressures from 2mbar to 200bar. The high grade range includes optional polished surface finish and various flanged connections to cover applications from pharmaceutical to offshore.

Custom Solutions

Not every system is the same and hence pressure regulators need to be sized and selected to provide an exact solution. The ability for a pressure regulator to provide stable control depends on pressures and flow rates within the system being able to pass through the seating area and cross holes within the valve. Other factors such as temperature, media, and external environment, provide variations that mean ‘off the shelf’ products may not be acceptable for many systems.

Custom Solutions

Examples of custom solutions are listed below, but we welcome the opportunity to discuss any specific application that requires an engineered product when ‘off the shelf’ won’t do
Flanged Pressure Regulators

Flanged Pressure Regulators

Pressure Tech developed the flanged back pressure regulator for use on Menthonal on a chemical injection system on board an FPSO. The 17-4PH seating provided positive shut off at 300bar set point, with flow capacity up to 80lpm. The regulator body was machined to accept class 2500 RTJ flanges, which were assembled by a coded welder and independently X-rayed before a full customer witness test. The option of flanged connections and various flange types can be applied to several of our pressure regulators. Please contact the office for further details.
Biased Pressure Regulators

Biased Pressure Regulators

Various applications require a combination of dome loading and biased spring loading to provide stable control under varying operating conditions. Maintaining a constant differential pressure across a fixed orifice provides a constant flow rate. Pressure Tech have supplied a range of positive and negative biased regulators on pressure reducing and back pressure regulators. Other biased designs include subsea regulators for use on hyperbaric chambers that must maintain a positive pressure within the chamber to prevent implosion as the depth of seawater increases.
