VISION STATEMENT

Pressure Tech’s vision is to achieve World wide recognition as a key manufacturer of stainless steel pressure regulators by offering exact solutions to all our customers. We will achieve this objective by continuous improvement, driven by product realisation, innovation, teamwork, and listening to the needs of our customers.

MANUFACTURER OF PRESSURE REGULATORS FOR THE OIL AND GAS MARKET

GAS ANALYSER & INSTRUMENTATION

HIGH PRESSURE & HYDRAULIC

BACK PRESSURE

HIGH FLOW

The function of a pressure regulator is to reduce a pressure and attempt to keep this pressure as constant as possible while the inlet pressure and the flow may vary.

What is a Pressure Regulator?

Oil & Gas Range

LGC-690 Series• Specially designed for control of low outlet pressures used on logic control systems

• Setpoint control within +/-1bar accuracy

Medium Flow/Back Pressure

MF-414H Series• Unique Ceramic seat for longer 5 times longer service life

• Balanced Main Valve

• Cv of 2.0

• Segregated Captured Vent

Sub Sea Applications

• The set pressure topside is referenced to the external depth of seawater pressure which directly increases the outlet pressure by a 1:1 ratio.

• Working with Cameron on sub sea application at 1300m depth.

• Will the seawater pressure be directly applied to the spring chamber area, or will there be an oil transfer chamber to protect the spring?

• If the seawater is in direct contact, and the spring is permanently submerged, we recommend to change the load spring to an elgiloy material, which will reflect in the pricing.

• Is the regulator in a permanent subsea installation or accessible for servicing?

LF-690 Series•Fully supported Main Valve within unique Seat Cartridge design to prevent ‘chattering’

or ‘unstable frequency resonance’

Sub Sea

Hydraulic LF-690

• 20,000psi inlet/outlet range• Ceramic seat design for water glycol

applications outperforms metal seated alternatives

• Unique seating design to reduce unstable control or ‘frequency resonance’

• Bottom entry access plug to drastically reduce service time

• Segregated captured vent• Range of high quality machined

sensing elements for precise and stable control

• Load bearings with large handwheel for low torque adjustment

• Baffle plate to protect the sensing element from the high velocity inlet pressure - encountered when the main valve opens

Test 2

Test 1

Rods of test materials (10mm diameter, 30mm long) were placed in the outlet stream of a high pressure water jet under the conditions indicated. The volume loss of each material was measured as a relative percentage of the volume loss from a 316 stainless steel control pin. The wear performance of the TX2000 is some 5-18 times better than that of the WC material

What we need to know

Can you please inform us on availability and feasibility of your pressure regulators for tube trailers. It seems that we have fairly good chance to develop that business here in China. This is a typical inquiry from local gas company:•Diaphragm pressure regulator•Pin: 200 bar•Pout: 10, option 20 bar•Gases: H2, He, N2, Ar, O2, CNG•Material: SS (316L)•Connectors: VCR (1/2“) or NPT (3/4“ or 1/2")•Cv > 2.0
