The API 600 / BS 1873 / BS 1868 family of Gate, Globe and Swing Check Valves is exceptionally sturdy, rugged and durable,
with a reputation for quality, integrity and long service. They are designed for tight sealing and ease of operation. The valves are
available with flanged ends or buttweld ends, in pressure ratings from ASME Class 150 to Class 1500, and in a variety of materials
of construction.
Gate Valves are of flexible wedge, outside screw and – yoke and bolted-bonnet construction. The valves conform to API 600.
Globe Valves feature a ball-type disc, outside screw-and-yoke and bolted-bonnet construction. They conform to BS 1873 and also
meet the general requirements of API 600, including shell wall thickness and stuffing box dimensions.
Check Valves are of swing-type and bolted-cover construction. They conform to BS 1868 and also meet the general
requirements of API 600, including shell wall thickness.

Types Features Advantages Applications
Gate Valve • Precision Finish Seat & Surface

• Fire Safe Design

• Back Seat Arrangement

• Ball Type Disc

• Suitable For Vacuum Service

• Easy Replacement

They have good shutoff characteristics.

• They are bidirectional.

• The pressure loss through the valve is


Socket or butt-welding end-gate

valves in air, fuel gas, feedwater,

steam, lube oil, and other systems

are typical applications. Threadedend

gate valves may be used in air,

gaseous, or liquid systems.

Globe Valve Precision Finish Seat & Surface

• Fire Safe Design

• Rotating Tip

• Linear or Equal

• % Characteristic

• Back Seat Arrangement

• Pressure Seal Bonnet

• Low Torque Quick Opening

• Good shut-off capability

• Moderate to good throttling capability

• Shorter stroke (compared to a gate valve)

• Easy to machine or resurface the seats

• With disc not attached to the stem, valve

can be used as a stop-check valve.

• Fuel oil system where flow is

regulated and leak tightness is of


• High-point vents and low-point

drains when leak tightness and

safety are major considerations.

• Boiler vents and drains, main steam

vents and drains, and heater drains.

Check Valve Full Flow Area

• Resilient Seat or Metal

• To Metal

• Low Head Loss

• They are self-actuated and require no

external means to actuate the valve either

to open or close. They are fast acting.

• Check Valve as we normally use in

plumbing, chilled or firefighting

system is normally a swing type

valve which can be specified for its

application which is not for any sort

of contamination or rugged used.
