Easy
operation

Description

The compact 3/4" drain valve was developed for draining or partially draining pool, water treatment, and piping systems.

Its design is tailored to the compatible check valves from Peraqua and Praher Plastics, allowing for direct installation without additional adapters or modifications.

The drain valve features a 3/4"-male thread that matches the connection dimensions of the compatible check valves. This allows it to be installed directly on the check valve and used as a designated drain point, for example, in lower sections of piping or upstream of specific system components.

This allows the affected section of the pipeline to be depressurized without having to dismantle any part of the pipeline.

Operation
simple and low maintenance

Description

The 2-way single union (SU) ball valve from Praher Plastics Canada is a high-quality, maintenance-friendly shut-off valve made of PVC for swimming pools, whirlpools, and water treatment systems. Its sophisticated design makes it particularly suitable for underfloor installations and flooded suction systems where static water pressure is constantly present.

Thanks to its compact design, high pressure resistance, and maintenance-friendly construction, this ball valve is ideal for private and commercial pool hydraulics.

Product details

	2-way ball valve SU
Housing material:	Grade 1 PVC
O-rings:	EPDM
Ball seats:	Polyethylene
Dimensions:	DN40 / d50 / 1½" - DN50 / d63 / 2"
Pressure rate:	PN10 (150 PSI)
Schedule:	80 bore
Connection:	1 x solvent socket end PVCu metric 1 x solvent socket end PVCu metric with union nut
Color:	Grey
Manufacturer:	Praher Plastics Canada

The integrated spare pin also serves as a tool for maintenance and repair work

Safety design for underfloor and flooded suction applications

The ball valve features a "below grade – blocked seat flooded suction design", i.e., a blow-out-proof valve seat design that was specially developed for installations below ground level.

Specifically, this means:

The valve seat is structurally blocked and secured from the inside so that it cannot be pushed out of the housing even under static pressure.
Even if the union nut of the single union is loosened when the pump is switched off, the valve seat remains securely in position.
There is no sudden escape of water or components, even though the pipe is still under gravitational pressure.

This safety feature is particularly important for pump sumps, underground piping, and all systems where the pump is installed below the water level.

Features

Single union design (SU), detachable on one side using a union nut: Enables quick disconnection of pipes without having to dismantle the entire pipe run – ideal for service, maintenance, and conversion work.
Locked ball seat with pin fastening: The retaining ring is fixed in the housing with two pins. This reliably prevents the ball or retaining ring from slipping unintentionally when the union nut is loosened.
Smooth operation even after long periods of inactivity: Due to its design, the load on the union nut is not transferred to the ball seat. This ensures that the handle remains smooth to operate at all times - even with valves that are rarely actuated.
When the pump is switched off, the valve seat cannot be pushed out by static water pressure even if the union nut is removed - a decisive safety advantage in pool operation.
Corrosion and chemical resistant: Resistant to chlorinated and salt water as well as common water treatment chemicals.
The integrated spare pin also serves as a tool for maintenance and repair work, for example, to remove the pin when servicing the valve seat.

Safety design for underfloor and flooded suction applications

The ball valve features a "below grade – blocked seat flooded suction design", i.e., a blow-out-proof valve seat design that was specially developed for installations below ground level.

Specifically, this means:

The valve seat is structurally blocked and secured from the inside so that it cannot be pushed out of the housing even under static pressure.
Even if the union nut of the single union is loosened when the pump is switched off, the valve seat remains securely in position.
There is no sudden escape of water or components, even though the pipe is still under gravitational pressure.

This safety feature is particularly important for pump sumps, underground piping, and all systems where the pump is installed below the water level.

Features

Single union design (SU), detachable on one side using a union nut: Enables quick disconnection of pipes without having to dismantle the entire pipe run – ideal for service, maintenance, and conversion work.
Locked ball seat with pin fastening: The retaining ring is fixed in the housing with two pins. This reliably prevents the ball or retaining ring from slipping unintentionally when the union nut is loosened.
Smooth operation even after long periods of inactivity: Due to its design, the load on the union nut is not transferred to the ball seat. This ensures that the handle remains smooth to operate at all times - even with valves that are rarely actuated.
When the pump is switched off, the valve seat cannot be pushed out by static water pressure even if the union nut is removed - a decisive safety advantage in pool operation.
Corrosion and chemical resistant: Resistant to chlorinated and salt water as well as common water treatment chemicals.
The integrated spare pin also serves as a tool for maintenance and repair work, for example, to remove the pin when servicing the valve seat.
