Overview of the Shipment
This week, a full range of stainless steel diaphragm valve units, from DN15 through to DN200, are being dispatched from KDV Flow UK. These comprise primarily Weir Type configurations in both manual and actuated variants, several with sealed bonnets, GR97 PTFE/Viton diaphragms, and DIN EN558-1 Series 1 lengths.
These valves are destined for various operations across mainland Europe, Spain, and the UK, supporting industries ranging from power generation and semiconductor manufacturing to chemical processing and marine systems.
This shipment reflects the continued demand for reliable stainless steel isolation solutions—ensuring operational longevity and compatibility with aggressive or critical media.
Stainless Steel Diaphragm Valve Range: Built to Handle the Application
The valves in this shipment include:
-
DN25–DN200 Weir Type stainless steel valves
-
DN50 units with GR97 diaphragms (PTFE/Viton)
-
DN65 hard rubber-lined units with extended handwheels
-
DN100 and DN125 units in DIN pattern with sealed bonnet assemblies
-
Stainless units fitted with KDV’s proprietary P-Series actuators
These are designed for chemical resistance, media separation, and robust lifecycle performance. The CF8M stainless steel construction ensures corrosion resistance in caustic environments while maintaining clean process flow—an increasingly preferred material in water treatment, pharma, and semiconductor sectors.
PTFE-lined valves and GR97 diaphragms are often specified for their inert properties, which are ideal for high-purity applications.
Common installations include:
-
Power generation in northern UK
-
Grit blasting systems in Italy
-
Semiconductor water systems
-
Marine valve installations (BSPP-threaded variants with PTFE diaphragms)
-
Chemical dosing skids

Regional Distribution & Industrial Service
A portion of these valves is bound for Spain, supporting industrial water systems and general process applications. Others are heading into the Benelux region, with a focus on general industrial process support and chemical service compatibility.
With Europe maintaining strict standards around metal grades, WRAS approvals, and DIN compatibility, KDV’s offerings are assembled to suit specific regional preferences—including options for ETFE, PFA, and Butyl linings where required.
Each valve is inspected against customer specification sheets and tested to ensure full compliance with both local standards and KDV QA benchmarks.

Warehouse to Workshop: How KDV Ships Stainless
All valves undergo 100% pressure testing, with specialist units such as the DN65 sealed bonnet assemblies and P-Series actuated DN80–DN200 valves receiving extended QA for actuation function, sealing integrity, and positioner setup.
In the case of lined options, KDV ensures full coating coverage and liner inspection before assembly. For this batch, final inspection included:
-
Visual and pressure test records
-
Seal compression checks
-
Batch traceability tagging
-
Stock preparation with secure packing protocols
Dispatch is completed from the Yorkshire facility, with packing designed for safe palletised international shipment, maintaining valve integrity throughout transit.
