Batley Valve Batseal (PTFE Lined) BV18000 Batley Valve Description The Batley Steadseal Valve incorporates a rubber seal clamped to the vane edge and is designed to ensure a uniform 360° seal contact in the closed position. The double eccentric action moves the vane into and out of the bodyseat with the minimum of wear and seating torque. This valve is particularly suitable where both tight shut off and control is required. For on/off service the valves can be operated manually with a worm and quadrant gearbox or remotely operated by pneumatic piston (rotary or cylinder), hydraulic or...

Batley Valve Batley Valve Materials Seal Materials NOTES: Intermittent operating temperature means peaking above the maximum continuous temperature for one to two minutes occasionally but not on an hourly/daily frequency. The Rubber Selection table should only be used for general guidance and full details of temperatures, line fluids, pressures, frequency of operations, velocities and vacuum conditions etc., should be included with your enquiry to ensure that the correct seal selection is recommended. The table opposite represents the most common materials of construction but it should be...

Batley Valve Batley Valve In the closed position without pressure there is a slight interference between the disc and the seat. The stainless steel support ring prevents any outward movement of the teflon seat, so retaining the sealing force. The seat is designed to move slightly in the direction of flow, this allows the pressure access to the back of the seat, thus making the seal progressively tighter as the pressure increases. Any slight deflection on the disc in the case of very high pressures, increases the tightness and shut off potential. Description The double offset design and...

Batley Valve Batley Valve Sizing & Selection Double Flanged Torques for Sizing Actuators - Inch-Pounds (R - P.T.F.E. Seat) Actuator selection is dependent upon a number of variable factors such as pressure drop across the valve, seat and bearing friction torques, cryogenic temperatures and flowing media. The figures in the following table are based on standard valves and materials working in normal service conditions. A safety factor as recommended by the actuator manufacturer should be applied. Consult Batley Valve for cryogenic torque figures. Nominal bore Dimensions shown as on...
