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

Tue, 05 May 2026 09:23:57 +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.

The key features of the M1 in detail

Modular design

Expandable from manual operation to fully automatic solutions - without replacing the base valve. Perfect for retrofittable or scalable system concepts.

Prepared for automation

The design of the M1 3-way ball valve is consistently geared towards easy installation and efficient automation. Domes and bracket are permanently integrated into the valve body, which means that the valve is prepared for actuator installation directly from the factory. Electric or pneumatic actuators can also be retrofitted after installation. Only an adapter set is required for automation.

For fixed-point mounting, an optional clamping element is available, while for flanged connections on flat surfaces a spacer element ensures correct positioning and stable installation.

Optionally available with position feedback or failsafe function.

Buttress thread

A buttress thread ensures that the union nut is securely seated, increases strength, and prevents it from opening on its own due to vibrations - for reliable support under all operating conditions.

Left-hand thread on the pressure rings

The left-hand thread on the pressure rings prevents accidental twisting when mounting the union nut, improves tightness, and ensures that the ball position remains securely set.

This reliably prevents the pressure ring from being accidentally unscrewed.

Safety handle with labeling plate

The new safety handle ensures maximum operating and maintenance safety: the clear correlation between handle and ball position, integrated locking lugs, and a tool for removing the pressure rings make handling particularly reliable. Correct installation is guaranteed by a precisely fitting lug on the stem, while individual labelling plates provide additional clarity.

T-ball for clear switching functions

Simultaneous connection of three lines: The T-bore can hydraulically connect two or three connections, allowing media to be distributed or mixed without additional fittings.

Mixing and distribution function in one component: The T-ball allows, for example, a second line to be mixed into a main flow or a volume flow to be divided between two outlets.

Robust & chemical-resistant

The M1 3-way ball valve impresses with:

High corrosion and chemical resistance
Resistance to chlorine and water treatment chemicals
Low pressure loss
Low operating torque

The double-sealed shaft and high-quality PTFE seat rings ensure permanent tightness in continuous operation.

Easy to service

Can be installed and removed radially. Maintenance and seal replacement are possible while installed. This reduces downtime and service costs.
