Valves for NH3

Here you will find a selection of some of the valves we can supply, regardless of it being for safety enhancement, throttling, shut-on or off or control of flow.

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.

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.

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.

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.

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.
