Vulcanised rubber lined butterfly valves developed to address a high quality, low cost valve, for use on corrosive line fluids such as seawater and brine.
The Batley Valve® BV 34000 vulcanised rubber lined butterfly valve incorporates a liner that is bonded to the valve body. This allows the valve to have higher closed differential pressures from full vacuum up to 20 bar g and the potential for higher fluid velocities up to 8 metres per second (dependent on valve size). The valve body incorporates a small raised spigot that prevents the body liner from being over compressed during installation.
The BV 32000 - Refractory lined is designed for temperatures above 1000C, or where higher pressures are involved, such as a water cooled design.
Experience of Refractory Lined Valves has been for gases at temperatures up to 1200ºC with low or negligible pressure. Materials of construction can vary considerably depending upon temperature, pressure, temperature fluctuation, flowing media, particularly in respect to oxidising or sulphurous atmospheres and clients own specifications. We recommend that the refractory cement lining is accurately cast into the body in our works to avoid problems on-site or in service.
The Batley Valve Metalseal design lends its self for use on higher temperatures and abrasive service where a PTFE seal would not be acceptable.
The Batley Valve® Metalseal Butterfly Valve is used in applications where high operating temperatures or abrasive service preclude the use of elastomer or polymeric seals, but a superior shut-off is still required. This design is an inherently fire safe design and has a shut-off to ANSI/FC I-70-2 class IV. Double offset design and geometry of the valve and seal combine to ensure a uniform 360º seal contact in the closed position. The double eccentric action of the disk minimises wear and seating torque. Hard surface deposits such as hard Chrome plating, Stellite & Tungsten Carbide are available.
The Batley Valve BV 22000 Hyperseal double offset is a versatile butterfly valve available in varied sizes and ANSI classes depending on the application.
Our standard Batley Valve® BV 22000 Hyperseal can be drilled to suit international standards up to class 300lb and special valves can be manufactured with bodies drilled to suit flanges up to ANSI class 2500lb. The seat is designed to move slightly in the flow direction, 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 of potential. 90º on/off action allows for fast operation and the low torque characteristics are an economic advantage in power operation.
This double eccentric rubber seal butterfly valve is designed to ensure a uniform 360 seal contact in the closed position.
The Batley Valve® Steadseal Valve incorporates a rubber seal clamped to the vane edge and is designed to ensure a uniform 360º seal contact in the closed position. The double eccentric action moves the vane into and out the bodyseat with the minimum wear and seating torque. This valve is particularly suitable where both tight shut-off and control is required. For on/off service the valve can be operated manually or by an automatic actuator.
The Batley Valve Batseal valve design incorporates PTFE to obtain maximum corrosion resistance for both shut off and control of line fluids.
This valve is bubble tight shut-off up to 10 bars depending upon operating temperature. Disk and spindle normally manufactured as a one piece unit. Lining moulded teflon FEP or virgin PTFE liner protects the body from the line fluid. Resilient silicone rubber backup strips between body and lining ensure positive contact with disk at all times.
The Batley Valve BV 16000 SpoolSeal butterfly control valve incorporates the use of a replaceable rubber liner for body protection.
Batley Valve® BV 16000 SpoolSeal butterfly control valves incorporate a replaceable rubber liner for body protection. The valves are normally supplied complete with our own manual, diaphragm, cylinder or electric actuator. The rubber lining is of snap-in type which locks into a body recess and is available in various grades of rubber. The streamlined shape of the vane provides minimum resistance to flow and the swing through action prevents damage to the liner should the valve overtravel. The body is of solid ring type accurately machined for liner retention, vane and spindle alignment to ensure positive shut-off combined with lower seating torques.
We developed Firesafe designs for petrochemical and offshore customers. A secondary metal seal is designed to maintain positive shut-off in case of fire damage to the PTFE seal.
Double offset design and geometry of the valve and seal combine to ensure a uniform 360º seal contact in the closed position. The double eccentric action moves the disc with the minimum of wear and seating torque. Fully rated to ANSI class 150lb and 300lb in sizes up to 600mm with sizes above on request. The Metalseal design lends its self for use on higher temperatures and abrasive service where a PTFE seal would not be acceptable. ANSI Class IV leakage is achieved. The valve can be supplied with a range of hard surface deposits such as hard Chrome plating, Stellite & Tungsten Carbide.
The Batley Valve BV 10000 Swingthrough is a versatile and robust control valve that is suitable for many process applications.
The standard range of Butterfly Valves has been designed to give cost effective flow control of liquids and gases where a complete tight shut-off is not essential. The 'swing-through' vane, which has no contact with the valve body, enables the valves to be used with high pressures and a wide range of temperatures. The standard has a basic 'equal percentage' characteristic but this is only true between the 10º and 60º open position. For control, 60 degree vane rotation is normally used and 90 degree vane rotation for on/off service
