Description

The M1 3-way ball valve with T-ball from Praher Plastics is a modular valve designed for applications in swimming pool, water treatment, and process engineering.

The valve is designed for switching and distribution tasks in filter circuits, solar bypasses, pool switching systems, and piping systems. The T-ball allows for precise control of flow paths without mixing of media.

Thanks to the modular platform and integrated domes, the ball valve can be equipped with suitable electric or pneumatic actuators. The true-union connections with union nuts allow the valve to be disassembled without disconnecting the piping.

Each valve is tested for leaks prior to shipment. The operating and service life values specified in the technical data refer to the operating conditions defined therein.

The key features of the M1 in detail

Modular design

Can be expanded from manual operation to an automated solution without replacing the base valve. Suitable for system designs that may require future expansions or modifications.

Prepared for automation

The design of the M1 3-way ball valve is optimized for easy installation of actuator components.

A dome and a mounting base are integrated into the valve body. This allows the valve to be prepared for retrofitting with electric or pneumatic actuators. Retrofitting is also possible while the valve is installed. A suitable adapter set is required for this.

A clamping element is available as an option for fixed-point mounting. For flange connections on flat surfaces, a spacer facilitates positioning and installation.

Optionally available with position feedback or a failsafe function.

Buttress thread

A buttress thread helps ensure a secure fit for the union nut and is designed for applications subject to vibration.

Left-hand thread on the pressure rings

The left-hand thread on the pressure rings reduces the risk of accidental rotation when installing the union nut and helps position the ball.

Safety handle with labeling plate

The safety handle ensures safe operation and maintenance. The correspondence between the handle and ball positions, integrated locking lugs, and a tool for removing the pressure rings make handling easier.

A form-fit connection to the shaft ensures proper installation. Custom label 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 features:

Corrosion-resistant materials
Resistance to suitable chlorine and water treatment media in accordance with material properties
Unrestricted flow
Low operating torque

The double-sealed shaft and PTFE seat rings ensure reliable sealing during normal operation.

Easy to service

Can be installed and removed radially. Maintenance and seal replacement can be performed even while the unit is installed.

The key features of the M1 in detail

Modular design

Can be expanded from manual operation to an automated solution without replacing the base valve. Suitable for system designs that may require future expansions or modifications.

Prepared for automation

The design of the M1 3-way ball valve is optimized for easy installation of actuator components.

A clamping element is available as an option for fixed-point mounting. For flange connections on flat surfaces, a spacer facilitates positioning and installation.

Optionally available with position feedback or a failsafe function.

Buttress thread

A buttress thread helps ensure a secure fit for the union nut and is designed for applications subject to vibration.

Left-hand thread on the pressure rings

The left-hand thread on the pressure rings reduces the risk of accidental rotation when installing the union nut and helps position the ball.

Safety handle with labeling plate

A form-fit connection to the shaft ensures proper installation. Custom label plates provide additional clarity.

L-ball for clear switching functions

Defined flow path without mixing. Suitable for priority control, bypass applications, and pool switching.

Robust & chemical-resistant

The M1 3-way ball valve features:

Corrosion-resistant materials
Resistance to suitable chlorine and water treatment media in accordance with material properties
Unrestricted flow
Low operating torque

The double-sealed shaft and PTFE seat rings ensure reliable sealing during normal operation.

Easy to service

Can be installed and removed radially. Maintenance and seal replacement can be performed even while the unit is installed.
