Stainless steel ball valve 780 3 way L-port

References 780-781: stainless-steel three-way threaded ball valves

Our references 780 and 781 are stainless-steel three-way threaded ball valves.

Three-way ball valves are mainly used to mix or distribute flows between three pipes. The valves can be mounted with a L-shaped ball or T-shaped ball. Depending on the port and position of the ball, three-way ball valves have various functions:

• Divert a fluid by closing an outlet pipe to redirect it to another pipe, closed in the previous position


• Mix liquids providing from two pipes into a third one


• Distribute a fluid from a single pipe into two outlet pipes

Our references 780 (L port) and 781 (T port) are made up of CF8M stainless-steel body and ball, and of a PTFE filled with 15% glass fibre seat. They have threaded BSP ends and come in multiple sizes (1/4" to 2"). These reduced-bore ball valves ensure tightness on three ways as they have four seats.

They are fitted with a number of specific technical items:

• Double antistatic device (small balls between stem and body and between stem and ball)


• Locking device


• Anti-blowout stem


• ISO 5211 mounting pad

Our stainless-steel three-way threaded ball valves allow a maximum pressure of 40 bar and temperatures ranging from -25 °C up to +180 °C.
