Engineered to meet European quality standards and optimized for high-demand Italian industrial and municipal waterworks.
Italy's water infrastructure landscape is undergoing a critical phase of modernization. Confronted by aging pipeline networks, complex regional topographies, and shifting climate patterns that alternate between severe droughts in regions like Sicily and Puglia and sudden torrential rainfalls in the northern basins, Italian water utilities (Aziende Municipalizzate) require robust flow management solutions. Over 40% of municipal water in Italy is lost through leakages, making active pressure management and precise hydraulic regulation paramount.
To curb Non-Revenue Water (NRW), Italian engineers increasingly rely on advanced diaphragm-operated water control valves, including Pilot-operated Pressure Reducing Valves (PRV) and Remote Float Control Valves. The implementation of strict regulations governed by ARERA (Italian Regulatory Authority for Energy, Networks, and Environment) demands that fluid systems comply with precise efficiency parameters, encouraging the deployment of durable ductile iron components rated for PN16 and PN25 operations.
"Modernizing Italian municipal and agricultural irrigation networks requires more than standard components; it demands pressure management valves engineered to handle fluctuating trans-apennine pressure differentials and corrosive soft-water environments."
Aligning global manufacturing capabilities with rigid European certifications to ensure maximum system reliability and environmental safety.
Urbanization and agricultural modernization drive global demand for diaphragm control valves. As a major global manufacturer, KR exports to 50+ countries, incorporating feedback from diverse climates into our manufacturing process.
All products destinados to Italy strictly comply with European standards including EN 1074-5 (Valves for water supply), CE marking, WRAS, ACS (Attestation de Conformité Sanitaire), and UNI EN ISO 9001:2015 quality frameworks.
From ductile iron (GGG50) bodies to specialized EPDM/NBR seals and epoxy coatings (minimum 250 microns), we tailor water control valves to withstand the varied mineralization levels of Italian municipal water networks.
KR has more than 20 years of experience in producing standard and non-standard valves of various types. We supply a wide selection of over 500 valve products, including butterfly valves, gate valves, check valves, water control valves, as well as all their matching and accessory products.
These products have applications in various industries such as water treatment, dam construction, commercial buildings, energy and heating, chemical engineering, etc. We have won high repeat purchase rates from customers with excellent product variety and quality.
Beyond product excellence, we are dedicated to creating a mutually beneficial partnership with every customer. We believe that reliable service is as crucial as superior products, and we strive to continuously optimize the customer experience to achieve long-term win-win cooperation.
Ensuring complete quality control from drawing board to the final delivery to pipeline networks across Italy and worldwide.
Our R&D department ensures product design and continuous innovation. Technicians design and develop products meeting custom and market requirements. Our lab provides extensive testing capabilities to elevate valve performance, currently supporting 20 series and over 500 varieties.
The production department formulates plans to guarantee timely delivery. Manufactured under strict ISO-9001 supervision, we leverage over 30 sets of machining equipment and update inventory monthly to exceed delivery expectations.
Zero leakage is our fundamental principle. According to international quality standards, the inspection department conducts comprehensive structural, size, and pressure tests (shell & seal testing) and issues detailed inspection reports before shipment.
How specialized valve combinations optimize municipal and industrial pipeline networks.
Utilizing 200X Pressure Reducing Valves in combination with flow control pilots enables municipal water authorities in Italy to divide cities into District Metered Areas (DMAs). This isolates pressure zones, reduces stress on old pipe systems, and lowers pipe bursts by up to 60%.
Utilizing 100X Remote Float Control Valves eliminates the risk of overflow in overhead storage tanks and ground reservoirs. These valves dynamically control water flow based on liquid levels without external electricity, utilizing the line pressure for pilot actuation.
Quick-closing check valves and slow-closing diaphragm control valves are integrated into pump stations in Italy to prevent severe shockwaves (water hammer) caused by unexpected power outages or pump start-up sequences.

Embracing Industry 4.0 integration, IoT monitoring, and low-carbon fluid dynamics.
As the European Green Deal drives digitalization in utility sectors, the traditional hydraulic control valve is evolving. Our R&D team is actively engineering integrated pilot solutions. By mounting high-precision solenoids, pressure transmitters, and RTU telemetry kits to our standard 200X and 100X valves, we enable remote set-point adjustment from centralized SCADA systems.
To resist mineral scaling and microbiological biofilm growth common in hard-water aquifers across Southern Italy, KR is testing advanced zero-VOC, high-build epoxy formulations. These coatings improve hydro-efficiency by reducing surface friction, thereby cutting energy consumption in municipal booster pump stations.
Operating under high differential pressures can cause rapid cavitation damage to pilot valves and valve discs. We provide customized anti-cavitation trim packages designed through Computational Fluid Dynamics (CFD), extending valve lifespans by up to 200% under severe flow conditions.

The 200X PRV is pilot-operated and diaphragm-controlled, designed to reduce a higher inlet pressure down to a stable, pre-set lower downstream pressure, regardless of flow fluctuations or inlet pressure changes. In municipal grids, particularly those with hilly topographies in Northern and Central Italy, this stabilizes grid pressures, minimizes leakage, and significantly reduces the probability of water pipe ruptures.
Water control valves supplied to the Italian market must align with EN 1074-5 (specific requirements for control valves), EN 1074-1, and carry CE marking. Additionally, materials in contact with drinking water must meet ACS, WRAS, or Italian DM 174/2004 regulations to ensure no heavy metals or toxic compounds migrate into the water supply.
The 100X valve is completely hydraulic-driven. It utilizes the kinetic energy and pressure of the fluid inside the pipeline. When the water level in the target reservoir reaches the set level of the pilot float, the float pilot closes, causing pressure to accumulate in the diaphragm chamber of the main valve, driving the valve disc closed. When the level drops, the pilot opens, releasing chamber pressure and opening the valve.
Ductile Iron contains graphite in spheroidal forms, which gives it higher tensile strength, impact resistance, and elongation characteristics compared to gray cast iron. It resists deformation under pressure spikes and thermal contraction, making GGG50 valves safer and more durable for municipal pipelines subject to hydraulic shocks.
Pilot-operated control valves require periodic checking of the pilot loop circuit. Pilot filter strainers should be cleaned of particulate buildup twice a year. Additionally, checking the rubber diaphragm for wear and verifying the pilot setpoint pressure ensures the main valve continues to throttle correctly without drifting over time.
