Service valve with internal thread and self-drainage

Resilient seated gate valve with optimum flow passage

• Suitable for drainage of pipes which might freeze e.g. irrigation pipes etc. In below ground applications sufficient draining for the valve has to be considered (e.g. drainage pit)
• Sealing system: Automatic secured drainage when valve is completely closed. No clearing when the valve is partly or completely open
• NOT suitable for sites with a drainage hole situated above the groundwater table

ISO-socket:

• The function of the ISO pipe fitting is clear and simple: the O-ring made of highly elastic elastomer seals even when depressurized due to its pretension on the pipe.
• As the water pressure and pipe tension increase, the sealing and grip rings are compressed further into the conical chamber, thus increasing the sealing and gripping effect
• The gripping and sealing functions only act on the outer diameter of the pipe; therefore only one fitting is required for all pressure ratings up to PN 16
• The joint is flexible; the fitting can be turned on the pipe and disassembled on demand without affecting the grip or seal. The installation of the fitting is quick and simple.

All ISO pipe fittings can also be supplied for PVC pipes with a spezialised grip ring at extra cost.
