They are used where minimum pressure drop andbi-directional on-off service is required. Normally Gate Valves are not designed for throttling service. Prolonged use in the partially open position will damage seating surfaces. Gate Valves are available with wedge configurations of solid and flexible type to meet the specific service conditions. Gate Valves normally are handwheel operated but are also available with gearing and electric motor actuator for remote Steel Bolted Bonnet Valves - BL SeriesYOKE BUSH : Furnished in Aluminium Bronze material.

Specify the type best suited to your service is the most common wedge type. It is also the strongest, simplest and highly resistant to vibration. It is not self-compensating to seat distortion caused by high temperature thermal expansion or bending WEDGECast Steel Bolted Bonnet Valves - BL WEDGE (Single piece) :The flex wedge is machined with a circumferential groove to allow the seating faces to move independently and adjust to movement of the body seats.

4 It is used where line loads or thermal expansion of the system is likely to distort the seat face in the valve. This type of wedge is not recommended for corrosive services but is ideally suited for steam or high temperature services . Flex wedge (Two piece) : Optional for bigger size Valves (sizes 14 and above). cast Steel Bolted Bonnet Valves - BL SeriesGate Valve - FeaturesGate Valve - FeaturesBody/ Bonnet joints on BHEL gate Valves are designed for rugged services . The standard joint varies depending on valve class. These standard joints are 150 - The standard, flat, oval Bonnet joint is the simplest configuration for low pressure services . Our standard gasket isflat asbestos but spiral wound gaskets are available for critical 300, 400, 600 & 900 - The circular male and femalebonnet joint is self-aligning and well suited for intermediatepressure classes.

They are suitable for service in horizontal or vertical (flow up through the valve only) piping runs.

10 Swing Check Valves have low pressure drop and are best suited for moderate velocity applications. Correct sizing of Swing Check Valve is important. Either too low a line velocity or too high a velocity will affect the valve function.
