Clack WS2H Softener Meter Controlled Valve 2" (Includes Internal Meter) V2HDME-05

The Clack WS2H Softener Meter Controlled Valve 2" (V2HDME-05) is a complete commercial-grade softener control valve supplied by WrekinWater, built around the same rugged WS2H platform used across large-scale water treatment installations, with an internal meter included as standard so regeneration is triggered by actual water usage rather than the clock. This 2" valve is intended for high-throughput softening plant serving commercial premises, hospitality sites, or industrial processes where consistent, capacity-matched softening is essential and downtime is not an option.

Technical specifications

Symptoms that mean you need this part

• The commercial softener is regenerating at the wrong times, or not regenerating at all, resulting in hard water reaching the site
• Water pressure through the softener has fallen away, pointing to a valve mechanism that is no longer flowing correctly
• Salt or brine usage has become erratic or excessive, a common sign the internal meter is misreading throughput
• Physical wear, cracking or seizing is visible on the existing 2" valve body after years of continuous commercial duty

Why it fails / why it matters

A commercial meter-controlled softener valve works constantly, measuring every litre that flows through the resin bed and initiating a full regeneration cycle once the calculated softening capacity is used up. Under sustained commercial flow rates, the internal meter's turbine and seals gradually wear, o-rings harden, and the valve body itself can suffer from mineral fouling, water hammer damage or piston wear, all of which reduce metering accuracy or stop the regeneration sequence from firing correctly — at that point the full valve and meter assembly generally needs replacing rather than a single component.

Why buy this from WrekinWater

WrekinWater has served more than 50,000 customers over 15 years from its base in Bettisfield, Shropshire, and stocks genuine Clack, Pentair Fleck, Autotrol and Kinetico parts suited to commercial specification jobs like this one. As a UK-registered company (Company No. 11000488) rated Excellent on Trustpilot, WrekinWater can supply this Clack WS2H softener valve assembly directly to your installer or water treatment engineer with accurate stock and technical support.

How to fit it

1. This is a commercial-scale valve assembly and must be commissioned by a qualified water treatment engineer or installer — do not attempt a DIY fit
2. The engineer isolates the softening system, releases pressure and closes the incoming water supply before starting work
3. The resin vessel is taken offline and the existing 2" softener valve and meter assembly is disconnected from the tank and site pipework
4. The new Clack WS2H V2HDME-05 valve, complete with internal meter, is fitted to the softener vessel and reconnected to the pipework and brine line
5. The engineer programmes the regeneration settings to match the resin volume, water hardness and site usage profile
6. The system is repressurised and put through a full regeneration cycle while the engineer confirms leak-free operation and correct meter readings
