Praher Plastics Canada drain valve for cone check valve, male thread ends 3/4", EPDM O-rings 1,78 €

Thu, 28 May 2026 13:07:25 +0200

Drain valve for cone check valve with 3/4" ET

Easy installation
simply screw on, done
Quick emptying
no dismantling required
Robust & durable
for long-term safe operation
Operation
simple and low maintenance

Description

A compact and extremely robust 3/4" drain valve, specially designed for the safe drainage or partial drainage of pool, water treatment, and piping systems. Its design is optimally matched to the cone check valves from Peraqua and Praher Plastics and allows for direct, precise installation - without any additional adapters or modifications.

The drain valve has a 3/4" male thread end, the geometry of which corresponds exactly to the connection dimensions of the matching check valves. This allows it to be installed directly on the check valve and acts as a defined drainage point, for example in deep pipe sections or in front of sensitive system components.

Since no pipe segment needs to be dismantled, the affected part of the system can be depressurized quickly, cleanly, and safely.
