Shut-off valve, DN25, Dimm (meters)

Shut-off valve, DN25, Dimm (meters), pulse-output water metering, distributed by DIMM.

Why meter water

Metering water means controlling it: metering and sub-metering track consumption point by point, fairly allocate costs between occupants or workshops, detect leaks by comparing indexes and bill on actual use. A reliable meter with a pulse output integrates into a supervision system (BMS) or remote-reading setup for automated monitoring with no site visit.

Principle

This shut-off valve isolates the meter or a network section for maintenance, without draining the whole installation. Durable body and internals (316L stainless, EPDM seals) for long service on potable water and technical networks.

How it works

Placed upstream and/or downstream of the meter, the valve eases removal and refitting of the device and secures interventions. Materials (PA, 316L stainless, EPDM) ensure sealing and pressure rating (PN10). Various diameters to suit the meter.

Applications

Applications: Isolement de compteur, Maintenance, Réseaux d'eau.

Specifications

Key strengths

• Isolates the meter for maintenance
• 316L stainless + EPDM seals
• Pressure rated (PN10)
• Eases removal/refitting
• Several diameters

Reliability & anti-fraud

A water meter's reliability lies in its design: dry dial isolated from the water, magnetic transmission between turbine and register (which also protects against magnet fraud), a hermetically sealed register to stay readable over time, and an epoxy-coated brass or corrosion-resistant cast-iron body. These choices ensure stable measurement and long life, even on lightly loaded water.

Remote reading & control

Paired with the pulse output, remote reading turns metering into a management tool: indexes are sent automatically to a supervision system or software, with no manual reading. You visualise consumption by point, allocate costs, spot overuse or a leak as soon as an abnormal flow persists at night, and trigger alerts. It is the basis for water saving and cost control.

DIMM metering range

This reference is part of DIMM's water-metering range: single-jet, multi-jet, Woltmann and combined meters, pulse emitters, protective strainers, isolation valves and accessories combine to build a complete metering point, from small domestic sub-meters to large remotely-read industrial meters.

Water saving & durability

Measuring better means consuming better: accurate metering and reliable remote reading reveal waste, encourage more frugal behaviour and quickly pay back the installation. Durable materials and a protected mechanism limit replacements, for a solution that is both economical and respectful of the water resource.

Choosing the right meter

Choosing a meter depends on the flow to measure and pipe diameter (DN), temperature (cold or hot water) and measuring range (ratio R). Single-jet meters suit small domestic diameters, multi-jet offer better low-flow accuracy, Woltmann handle high flows with low pressure drop, and combined meters cover a very wide range. DIMM helps size to your installation.

Installation & maintenance

Installation is on a full pipe, in the arrow direction, preferably horizontal to preserve accuracy (maximum ratio). Follow the recommended upstream/downstream straight lengths and fit a strainer upstream to protect the mechanism. Isolation valves ease removal. Maintenance is minimal: periodic checks and replacement at metrological end of life.
