Dispenser control valve

High Quality Components and Complete System Solutions for the Compressed Natural Gas industry

CNG Solenoid Valves

Norgren has been supplying high pressure valves to customers manufacturing CNG compression and dispense systems since 1996. With pressures up to 350 bar, we understand the need for valves to be safe, have very high levels of pressure integrity and to be reliable - particularly with regard to the high number of switching cycles that a typical valve needs to perform.
Due to the requirement for zero internal and external leakage, we have to ensure the highest standards of production, coupled with premier quality materials in the design and manufacture of our valves.

Proportional pressure control valves

Functioning in the same way as the spring and dome loaded regulators, except the output pressure is controlled by an electrical signal. They can be used to control the pilot pressure onto a dome loaded pressure regulator and therefore automate a pressure control process.
Port sizes: 1/4” or flange mounted directly on dome loaded regulator
Pressure range: up to 420 bar
Temperature range: -20°C to +80°C
Control signal: 4-20 mA or 0-10V
Internal closed loop control
Body materials: brass or aluminium bronze

Stop valves

Shut off the flow of gas enabling maintenance and service access to the CNG system.

Balanced needle valve construction enabling constant low torque adjustment.

High pressure tight integrity
Port sizes: 1/4” to 1”
Pressure range: up to 420 bar
Temperature range: -20°C to +80°C
Body materials: stainless steel, aluminium bronze or brass

Station valve manifold

Solenoid valve manifold with integrated check valves which can be used in priority panels and even in a bus or truck dispenser

Spring loaded regulators

Pressure regulators (reducers or controllers) control the outlet pressure over a range of varying inlet pressures and flows.
Regulators are sometimes called ‘Forward Regulators’ to prevent confusion with back pressure maintaining valves.
Manual adjustment via knob
Port sizes: 1/4” to 1”
Pressure range: 100 to 420 bar
Flow rate: up to 1000 Nm3/h
Temperature range: -20°C to +80°C
Body materials: aluminium bronze, brass or stainless steel

Pressure relief valves

The valve opens to the atmosphere if the inlet pressure rises above the pre-set point. Excess pressure is therefore relieved from the system in a safe and controlled manner.
Port sizes: 1/4” to 1” 1/2
Pressure range: up to 450 bar
Pre-set pressure range: up to 450 bar
Tamper proof seal
Body materials: aluminium bronze, brass or stainless steel

CNG Tube fittings

Connect components and pipe work in the CNG system.3 piece flat face sealing construction enabling system components to be removed without disturbing the pipe work installation

Connection sizes: 1/8” up to 3”
Tube sizes: Ø 4 to 80mm
Pressure range: up to 420 bar
Temperature range: -20°C to +80°C
One end available for but or socket welding
Materials: brass, aluminium bronze or stainless steel

Solenoid coil For pressure solenoid valves

The interchangeable coil system on our CNG valves enables us to select from our extensive range of globally approved coils to match with the required approval and meet the demands of the most hostile of environments

Dome Loaded Regulators

Functioning in the same way as the spring loaded pressure regulator, but rather than using a manually adjusted spring, force is applied to the control element (diaphragm or piston) by pressure inside the dome of the regulator. The pilot pressure can be applied from a proportional valve, or a small low flow spring loaded regulator.
Particularly suited to high flow applications
Can be remotely electrically adjusted by using a proportional valve
Port sizes: 3/8” to 3”
Pressure range: 100 to 420 bar
Flow rate: up to 10 000 Nm3/h
Temperature range: -20°C to +80°C
Body materials: aluminium bronze, brass or stainless steel

Non return valves

Used to prevent the back flow of media.
Port sizes: 1/4” to 1”
Pressure range: up to 420 bar
Temperature range: -35°C to +120°C
Materials: brass or stainless steel

Inline filters

Particle contamination at high pressures will reduce the service life of CNG control equipment, in-line filters provide protection against particle ingress.
Port sizes: 3/8” to 3”
Pressure range: up to 750 bar
Temperature range: -40°C to +150°C
Filter element: 5, 15 or 25 micron stainless steel mesh or sintered bronze
Body materials: brass, aluminium bronze or stainless steel
