High-durability filtration solutions designed to meet the rigorous standards of New Zealand's industrial infrastructure.
New Zealand's unique industrial landscape demands fluid control components that can withstand diverse and demanding environments. From the geothermal energy fields of the Taupo Volcanic Zone to the high-sanitation dairy processing plants of the Waikato, and the municipal water networks of Auckland and Wellington, pipeline integrity is paramount. Y-Type strainers serve as the critical first line of defense, protecting expensive downstream equipment like pumps, control valves, and flow meters from particulate damage.
As a leading global valve manufacturer, KR Valve Group provides high-performance Y-type strainers engineered specifically to meet the compliance standards and environmental challenges of the New Zealand market. Our products ensure operational continuity, minimize maintenance downtime, and guarantee compliance with local regulations, including the Pressure Equipment Regulations (PECPR).
Sanitation and corrosion resistance are non-negotiable. Our CF8 (SS304) and CF8M (SS316) stainless steel Y-strainers feature precision-woven mesh screens that prevent contamination in Clean-in-Place (CIP) systems and raw milk processing lines.
High temperatures and corrosive hydrogen sulfide (H2S) gas require robust WCB carbon steel strainers. Engineered for high-pressure classes (ANSI 150LB/300LB), these strainers ensure safe and continuous energy production.
How our Y-Type strainers solve specific engineering challenges across New Zealand's key sectors.
In municipal water networks managed by entities like Watercare Auckland or Wellington Water, ductile iron GGG40 Y-strainers with fusion-bonded epoxy coatings are deployed. Conforming to AS/NZS 4020, they guarantee that drinking water remains free of rust, scale, and debris without leaching harmful substances into the supply.
For commercial heating and cooling loops in the Christchurch rebuild and Auckland CBD high-rises, cast iron GG25 flanged Y-strainers are the industry standard. They protect chillers and boilers from installation debris, maintaining system efficiency and reducing energy consumption.
New Zealand's extensive maritime industry requires strainers that resist saltwater corrosion. Our bronze and super duplex stainless steel Y-strainers are optimized for sea-water cooling systems, ballast water treatment, and offshore processing facilities.
Ensuring alignment with New Zealand's strict regulatory frameworks and international engineering codes.
In New Zealand, pressure equipment must comply with the Health and Safety at Work (Pressure Equipment, Cranes, and Passenger Ropeways) Regulations 1999 (PECPR). KR Valve Group ensures that all Y-type strainers supplied to the NZ market undergo rigorous design verification and pressure testing.
Our manufacturing processes are certified under ISO 9001:2015, and our products conform to international standards including ASME B16.34, DIN 3202, and BS 2080. For potable water applications, we offer materials certified to AS/NZS 4020, ensuring complete safety and compliance.

The future of fluid control lies in predictive maintenance. KR Valve Group is currently developing a technical roadmap for "Smart Y-Strainers". By integrating differential pressure (DP) transmitters and IoT-enabled sensors, operators in remote New Zealand locations (such as South Island agricultural hubs or geothermal fields) can monitor screen clogging in real-time.
This technology prevents cavitation in downstream pumps, reduces manual inspection schedules, and allows for scheduled maintenance before system failure occurs. Partnering with KR Valve means aligning your business with the cutting edge of industrial valve technology.
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 valve, gate valve, check valve, water control valve, 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.
