About Pressure Tech
Introduction
Welcome to Pressure Tech
Established in 2000, I am proud to say that Pressure Tech is a family business with customer service and quality at the heart of our operation. Equally, we pride ourselves on having the technical know-how and professionalism typically associated with larger corporate companies.
Based in the North-West UK, our facilities house the entire process from design, manufacturing and assembly through to sales, purchasing and accounts. The Pressure Tech name is now recognised globally for manufacturing high-quality pressure regulators, and we are supported by a worldwide network of Authorised Resellers.
Steve Yorke-Robinson Managing Director of Pressure Tech
We passionately believe that our products and all-round service represent a market-leading offering, and here’s why:
EXPANDING OUR EXPERIENCE Our team of over 40 people includes a combination of long-term employees offering extensive product experience and understanding of the applications they have been used on, with the more recent addition of employees who have added specialist knowledge in areas such as strategic business management. It is this blend that continues to add strength and value to our core business of designing and manufacturing high-quality pressure regulators.
PARTNERING WITH CUSTOMERS Whether it’s offering general advice or help finding a specific solution to an application, our close-working internal infrastructure allows us to respond to questions promptly and effectively to allow our customers to make quick decisions with confidence. Not every system is the same and sometimes ‘off-the-shelf’ products may not be suitable for some applications. Our sales and design teams work closely with customers to ensure products are designed to meet their exact needs.
GLOBAL REACH Our products are used worldwide with 70% being exported for use on critical high-pressure control systems such as wellhead control panels, gas analyser systems, hyperbaric diving systems and the latest hydrogen technology. We continually listen to customer feedback to ensure product realisation is achieved. Our products are supplied to an ever-increasing customer base ranging from family businesses like our own to blue chip multinationals, meaning we offer a personal touch combined with the capacity to fulfil larger projects.
Introduction
In-House Capabilities...
QUALITY
As a company we have always understood the critical importance of maintaining quality throughout our business. We constantly aspire to provide products and services that not only meet, but exceed the requirements of our customers.
It is our long-term commitment to quality that has created a ‘quality culture’ here at Pressure Tech. When decisions are made, be it to the design of a product, the sourcing of raw materials, or the processes under which we operate, quality and the requirements of our customers are of primary consideration.
DESIGN
MANUFACTURING
ASSEMBLY
We take great pride in being able to design bespoke solutions to fulfil customer requirements. This in-house service is one of the many reasons why existing customers come back to us time and again, and why, off the back of recommendations, new customers approach Pressure Tech when an off-the-shelf product just won’t suffice.
Our in-house machine shop is operated by an experienced team of machinists and is overseen by our Operations Manager. Regular investments in machinery ensure we have the capacity to maintain stock of ‘standard’ components for competitive lead times, and to provide the production flexibility to quickly respond to urgent customer requirements.
Our in-house team of skilled assembly and testing engineers work closely with our design and manufacturing departments, whilst workload is strategically managed and scheduled by our Planning Manager using the latest shop-floor loading software. This strategic approach ensures customer orders are fulfilled on-time.

Flanges and ordering information
Flanges
Bolted Flanges...
In addition to NPT, BSPP and medium pressure fittings, we also offer flanged connections on our full range of Pressure Tech regulators. Flanges offer easy maintenance, repair and inspection, and are typically used on Chemical Injection and Produced Water Systems.
Traditionally our flanged connections have been supplied welded, but this is a time consuming process. Every order including a welded flange required a full design overview to ensure the correct weld ends were selected for each application.
Our Engineering team worked to provide an alternative solution. Our bolted flange concept is based on three standard modular designs to cover up to class 4500, and created to accommodate any of our pressure regulators. These are:
RANGE CLASSES PRESSURE RATING
Up to Class 600 150 300 600 Up to 99.3 bar
Up to Class 2500 900 1500 2500 Up to 413.7 bar
Up to Class 4500 4500 - - Up to 744.6 bar
MODULAR DESIGN
STANDARDS TIME SAVING
Our bolted flange concept is based on three standard modular designs to cover up to class 4500.
The bolted design for flange connections conforms to a range of standards including:
Time savings include:
- No requirement for subcontract welding • Only need to programme three body set-ups, reducing machine set-up times • Straightforward assembly
- ASME 16.5 • API • DIN • Grayloc
This allows us to offer bolted flange connections onto any pressure regulator within our product range.

Cv Formulae...
The Cv or flow capacity of a regulator is the maximum flow capability of a regulator (i.e. when the regulator is fully open) under a specific set of conditions. The Cv calculation varies based on the media used in your application.
Please refer to the relevant formula below to calculate the Cv for your application:
For Liquids (e.g. Water, Oil etc)
FORMULA KEY NOTES
Specific gravity correction is neglible for water below 93°C (200°F) - use S=1.0.
Cv: Valve flow coefficient (US GPM with P=1 psi) Q: Fluid flow (US GPM) S: Specific gravity of fluid ∆P: P1 - P2 at maximum flow (psi)
Use actual specific gravity of other liquids at actual flow temperature.
Cv: Valve flow coefficient (US GPM with P=1 psi) K1: Viscosity correction factor for fluids Q: Fluid flow (US GPM) S: Specific gravity of fluid ∆P: P1 - P2 at maximum flow (psi)
Use this formula for fluids with viscosity correction factor.
Use actual specific gravity of other liquids at actual flow temperature.
For Gases (e.g. Air, Natural Gas, Propane, etc)
FORMULA KEY NOTES
Cv: Valve flow coefficient (US GPM with P=1 psi) Qa: Air or gas flow (SCFH) at 14.7 psi and 60°F G: Specific gravity of gas relative to air at 14.7 psi and 60°F T: Flow air or gas temperature (°F) ∆P: P1 - P2 at maximum flow (psi) P2: Outlet pressure at maximum flow (psi abs.)
Use this formula when P2 is greater than 50% of P1.
Cv: Valve flow coefficient (US GPM with P=1 psi) Qa: Air or gas flow (SCFH) at 14.7 psi and 60°F G: Specific gravity of gas relative to air at 14.7 psi and 60°F T: Flow air or gas temperature (°F) P1: Inlet pressure at maximum flow (psi abs.)
Use this formula when P2 is less than or equal to 50% of P1.
