Gas valves for LPG service

Gas valves come in many shapes and sizes, with different functions and roles in a gas system. Common to them all is that they allow you to control the flow, pressure and direction of liquid and/or vapour.

We do our best to keep up with the ever expanding and innovative market of gas valves for LPG. The selection spans over mechanical, digital and electromechanical gas valves to suit all LPG related purposes and applications. Whether it is pressure control, bypassing, shut-off, excess flow check, pressure relief or multi valves that is needed, this is the place to find them.

Back check valves (flanged)

These one-directional valves close off if the flow direction changes or flow stops. They keep the contents of a container from escaping if the piping or fittings accidentally break.

Back check valves (threaded)

One-way valves that prevent the contents of a container from escaping if the piping or fittings unexpectedly break. Back check valves close off if the direction of flow changes, or if flow stops.

Ball valves

Operated by a simple 90˚ turn of a lever, ball valves can either fully permit or restrict flow. They are simple and fast acting valves for on/off operations.

Bypass valves

Protect your pumps and other components from damage by a build-up of overpressure. Bypass valves minimise wear on other pipe units and ensure easy maintenance.

Differential pressure valves

Available in mechanical or digital, differential pressure control valves often work with meters and vapour eliminators and are controlled by pressure differences or electrical signals.

Emergency shut off valves

Also known as ESV’s, these vital safety units respond to extreme changes in pressure, flow and temperature and will shut off flow both up and downstream of the valve.

Excess flow valves (flanged)

Normally open and bi-directional, these valves will shut the flow if the rate of flow exceeds an expected rate, until the pressure is close to equalised.

Excess flow valves (threaded)

A threaded excess flow valve is a bi-directional valve that shuts off flow in one direction if it exceeds a predetermined value. Its bleed-off feature assists in pressure equalisation.

External relief valves

In places where pressure can build to unsafe levels and cause dangerous situations, these relief valves provide added security for both people and equipment.

Globe and angle valves

In the service pipelines of places like filling plants, bobtails, transports and bulk storage containers, globe and angle valves can regulate or completely shut off flow.

Internal pressure relief valves

Available in fully or semi-internal types, internal pressure relief valves (or internal PRV’s) provide over-pressure protection for mobile tanks and containers.

Internal valves

As a safety measure to prevent spillage in case of damaged piping or tipped-over tanks, internal valves are important elements of LPG storage tanks.

Multi valves

Essentially a body containing many valves and functionalities, multi valves are specifically designed to fit in ASME containers with a single opening.

Multiports

On large stationary tanks with flanged connections, multiport manifold valves enable maintenance of relief valves without evacuating the contents of the vessel.

Needle valves

By allowing users to accurately control the flow and pressure of vapour and liquids, needle valves protect delicate gauges in pipework from pressure surge damage.

Safety relief valves (SAL) – vapour

Type SAL safety relief valves are a last-in-line defense against the unintentional activation of shut-off valves, preventing dangerous overpressure by ensuring fast relief.

Service valves (liquid)

Liquid and vapour withdrawal service on ASME motorfuel containers equipped with capacity sufficient relief valves. The valves can be tailored to the given system they will be installed in.

Service valves (vapour)

Vapour withdrawal service on ASME and DOT containers equipped with capacity sufficient relief valves. The features can vary according to the specific requirements of the given system.

Shear valves

Also known as fire and crash valves, shear valves provide a critical, bi-directional shut-off safety function for autogas dispensers in case of impact or dislodgement.

Solenoid valves

Electromechanical valves that act depending on the digital signals they receive to control the flow of gas. They come with slow opening and fast closing actuators.
