Valves
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.
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.
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.
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.
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.
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.
Multiports
On large stationary tanks with flanged connections, multiport manifold valves enable maintenance of relief valves without evacuating the contents of the vessel.
Multi valves
Essentially a body containing many valves and functionalities, multi valves are specifically designed to fit in ASME containers with a single opening.
Needle valves
A small but extremely important element to electrical project supply, conduit fittings may cost little but are extremely important. Rafah baghdadonly provide the very best quality conduit fittings as our aim is to provide reliable electrical installations.
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
These electromechanical safety devices control the gas supply to appliances and pipework. Typically installed in pumping equipment, metering units, filling systems and tanks.
Switchover valves
These valves allow flawless changeover between gas cylinders for continuous supply and minimal pressure loss. The switch can happen automatically or manually via a lever.
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.
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.
Vent valves
Designed to bleed off trapped liquid and help indicate when a tank is filled to its maximum capacity. Often used together with globe and angle valves
