Diaphragm valve T7 with torque limiting

Safety and performance like never before!
The revolutionary diaphragm valve T7 sets new standards. By combining multiple innovative features and increasing performance and safety, our engineers have succeeded in developing a truly unique diaphragm valve.

Our new price list went online at the beginning of the year. More facts and information you should know about the diaphragm valve T7 can be found there. If you would like to receive more information about our products, browse online through our new price list and our updated product brochure.

What is a diaphragm valve?
Fluids can be controlled with diaphragm valves. Valves based on the membrane principle prevent deposits, that’s why they are also referred to as the least dead space operating principle.

T7 diaphragm valve from Praher Plastics
One of the many benefits from our T7 is the fully open limit stop. This function prevents the valve from sticking when left in the open position for prolonged periods. Additionally, the ergonomically shaped non-slip handwheel allows easy operation with one hand and the new body shape ensures that water and other fluids drain off completely.
Nine convincing arguments for our T7
Patented Engineering – Convincing Performance!

Torque limiter
Prevents overturning of the handwheel and protects the diaphragm

Fully open position limit stop
Prevents the valve against sticking, when it is fully open for a longer period

Increased nominal pressure rating
20% higher than previous model

Ergonomic handwheel
Non-slip for simple and safe operation with one hand

Special body geometry
Allows fluids to drain off the outer surface of the valve

Detent
Simple and secure locking mechanism

Visual position indicator
Simple and effortless valve opening position indicator

Clear markings
Guides for correct installation of the valve

Visible markings
Helps to identify installed components without disassembling the valve

The right material for every application
The T7 Valves are available in three different materials:
PVC Model
Polyvinyl chloride has been proven to be physiologically harmless and is therefore particularly suited for direct contact with drinking water and food.
PP Model
Polypropylene, with its good mechanical properties and great dimensional stability under heat, is suitable for industrial applications.
PVDF Model
Polyvinylidene fluoride possesses outstanding chemical, thermal and mechanical stability, making it the ideal solution for extremely demanding applications.

A selection of two different diaphragms is also available:
PTFE Diaphragm
Valve diaphragms coated with polytetrafluorethylene (also known as Teflon) are characterised by strong resistance to a huge range of chemicals.
EPDM Diaphragm
Valve diaphragms made of ethylene propylene diene nonomer rubber possess great chemical and thermal resilience and are therefore particularly well suited for pipes used to transport hot media or aggressive chemicals.

What accessories and spare parts are available for the T7?
For the accessories and spare parts for the T7 you can choose between a handwheel with or without torque limitation. The upper part and the membrane are available as spare parts. For the connections for the screw type you can choose between all inserts of the IBG range and the diaphragm valve spare parts. The PLS (Praher Labeling System) is available in four colours for the T7 diaphragm valve. Mounting plates as mounting aids and/or for height compensation are available as accessories.
