Short Pattern Flanged Ball Valves
A short pattern flanged ball valve is a full bore ball valve with a two piece cast body whose face-to-face length has been shortened. It saves space in boiler rooms and pump sets where long body valves do not fit.
The body and cover are made of grey cast iron and the ball of stainless steel or ductile iron. Products are offered from DN40 to DN250 with PN10 and PN16 flange drillings.
Main Applications
- Hot water and central heating distribution lines
- Cooling water and chiller circuits
- Condensate return lines
- Boiler room header outlets
- Suction and discharge lines of pump sets
- Main shut-off points in building mechanical installations

Advantages
Space Saving
- The short face-to-face length fits tight boiler rooms.
- Valve replacement on existing lines becomes easier.
Full Bore
- Pressure drop equals that of a pipe of the same size.
- Pump head is not wasted across the valve.
Double Sealing
- The stem is guided by a PTFE and O-ring system.
- Mounting from inside gives an extra sealing safeguard.
Hot Water Resistance
- Operates up to 180 °C.
- Suitable for central heating and condensate lines.
Construction and Design Features
- The body consists of two parts with the flanges cast integrally.
- The operating stem is fitted from inside the body.
- The ball sealing ring and stem ring are PTFE; the outer sealing ring is silicone.
- On DN250 the ball has a reduced bore.
- The handle is fixed to the stem with a nut and has a plastic coating.

How to Choose?
- Check the flange drillingConfirm that the mating flange is drilled to PN10 or PN16.
- Compare the temperatureIf the medium exceeds 180 °C, move to another body type.
- Measure the installation lengthWhen replacing on an existing line, compare the face-to-face length with the datasheet table.
- Choose the ball materialPrefer a stainless ball model for condensate and oxygenated water.
- Allow for the weightPlan pipe supports for the valve weight at DN150 and above.
