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.
