Valves

GATE VALVE

GLOBE VALVE

DIAPHRAGM VALVE

Common valve used mainly as Open/Closed for Liquids. Screwed/Flanged. Bronze/Cast /Stainless Steel. 15 mm to 600mm Robust Valve used to regulate flow of water & fuels. Bronze /Cast & Stainless Steel Screwed/Flanged 15mm to 600mm< Versatile Valve for many applications.Diaphragm changed with Valve in place.Diaphragms for Water, Fuels & Acids. Weir type for flow control or Straight through types. Flanged or Screwed.15mm to 350mm.

BUTTERFLY VALVE WAFER TYPE

DOUBLE FLANGED BUTTERFLY VALVE

LUGGED TYPE SCREW HOLES

Butterfly Valves are relatively lightweight in larger sizes. Common sizes range from 50mm to 600mm and larger made to Order. Easy to install into piping systems.The body liner in smaller sizes effects a perfect seal between body & flanges. Manufactured in Cast Iron & Stainless Steel with liners & discs to suit most applications.


DUO-CHECK VALVE

TILTING DISC CHECK

PISTON CHECK VALVE

Check Valves are designed to protect pumps & equipment from harmful backpressure. Duo-Check valve can be installed in both horizontal & vertical positions. It is good engineering practice to fit a counter weight to Swing-Check & Tilting Disc Valves.

FLOWMETERS

PRESSURE & TEMPERATURE GAUGE WATER, OIL AND GAS

DIAPHRAGM VALVE

Common valve used mainly as Open/Closed for Liquids. Screwed/Flanged. Bronze/Cast /Stainless Steel. 15 mm to 600mm Robust Valve used to regulate flow of water & fuels. Bronze /Cast & Stainless Steel Screwed/Flanged 15mm to 600mm< Used to strain contaminates from pipeline liquids to protect control valves & equipment. Mesh made of stainless steel Perforations ranges 0.8mm to 3.0mm. Should be drained & cleaned regularly.

NEEDLE VALVE

Used for fine regulation & isolation of flow to instrumentation

 VALVE

Installed where it is required to reduce from one pressure to another and to maintain reduced pressure on the downstream side irrespective of fluctuations on inlet pressure or flow..

 PLUG VALVE

Quarter turn operation from fully open to fully closed provides quick action and flow is straight through the valve with no sudden alteration in shape or section so that pressure head loss due to valve is low

 

 

 

 

Safety Valve Flanged & Screwed – Steel – Stainless & Bronze

Safety or Pressure Relief Valves are suitable for most general applications where a Safety device is required on pipelines, pumps & vessels to automatically relieve excess pressure then reset to system design pressure to prevent ruptures and water hammer. Used on liquids & compressed air


 

 

 

 

Pipeline Expansion Joints

Manufactured in screwed and flanged types. Single & twin sphere to absorb flexing, sound and vibration in pipelines.


SELENOID VALVE

KNIFE GATE VALVE

DUCK BILL CHECK VALVEDIAPHRAGM VALVE

Common valve used mainly as Open/Closed for Liquids. Screwed/Flanged. Bronze/Cast /Stainless Steel. 15 mm to 600mm Designed to cut through media prior to closure. Suited to paper & pulp industry and light slurry such as mine tailings dams. Lightweight & easy to install Used on dams & weirs. Simple design no moving parts.

 

 

SHIP VALVES

Ships Valves Ships use Globe Valve extensively throughout the vessel. Screw-Lift Globe Valves are used to regulate flow of liquids. Screw-Down-Non-Return types are generally used in bilge systems to prevent backflooding, as feed check valves or as boiler stop valves. They have a dual purpose, acting as flow control and backflow prevention. Sight Checks are used to visually check the flow of liquids. Engine shut-off valves are used in emergency situations to shut off fuel to the engine room, usually manually operated from the bridge. Storm Valves are mainly installed in sanitary piping which have a ships side exit. They will prevent seawater entering this system during heavy seas.
