View Product Specifications →Switzerland's industrial and building technology sectors represent some of the most demanding markets globally. The country's strict environmental mandates, encapsulated in regulations like the MuKEn 2014 (Mustervorschriften der Kantone im Energiebereich) and Swiss standard SIA 384/2, demand absolute efficiency and thermal integrity in energy distribution networks.
For district heating (Fernwärme) and geothermal loop systems in cantons like Zurich, Geneva, and Bern, flow control components must operate continuously with zero leakage under high pressure cycles. Brass alloy composition must adhere strictly to SVGW guidelines to prevent lead leaching into drinking water supplies. Swiss engineers favor solutions that reduce system pressure drop, thereby shrinking pump energy consumption and supporting Switzerland's overall energy transition targets.
In response, our supply chain has integrated precision machining workflows specifically matching the requirements for low-lead and lead-free alloys, certified to match or exceed European standards such as EN 13828.
From our manufacturing capital hub to international markets, we engineer dependability into every valve connection.
How our advanced production ecosystem in Yuhuan, China, aligns with Swiss procurement quality and speed.
Leveraging over 80 sets of specialized machine tools within our 600+ equipment inventory, we eliminate human variability in core dimensions. Automated multi-axis machining ensures that internal seats and ball tolerances remain under ±0.01mm, ensuring tight shut-off characteristics.
Our Quality Policy statement, "Fine work, no leakage," is driven by automated pneumatic and hydraulic testing stations. Every individual ball valve undergoes seat and body testing at 1.5 times nominal pressure before packaging, preventing onsite failures in remote Swiss heating loops.
Through optimized container routes and digital order tracking, we guarantee reliable lead times to European distribution hubs. Our dedicated Cokaren brand acts as our dynamic platform for refined components, fulfilling the strict demands of European and North American OEM distributors.
A comprehensive component blueprint optimized for high-performance hydronic heat loop balancing.
Modern buildings in Alpine regions require balanced water loops. The diagram below illustrates how our custom components work in harmony, from water entry filtration to smart thermostatic mixing and floor distribution, designed to ensure stable temperatures and long mechanical life.
Water Filter Y9021 removes 98% of line impurities, safeguarding downstream controls.
Boiler Angel Valves Y5001/Y5002 with spherical spools isolate boiler systems.
Mixing Shunt Y5020 balances cold and hot streams, stabilizing delivery temp.
Manifold Y1001 distributes balanced hydronic flow to distinct zones.
Our Y2010/Y6012 valve designs consolidate air release, thermostatic regulation, and isolation in a single unit, avoiding complex multi-part configurations in narrow cabinet installations. The addition of automated air release with our Venting Valve Y9070 guarantees system pressure optimization, preventing cavitation in water heaters and solar thermal setups.
To complement mechanical valves, the Smart Thermostat Y9031 integrates localized sensor data to actuate manifold zones. This integration provides Swiss building owners with verifiable energy consumption reductions, helping meet high energy certifications like Minergie.

We primarily utilize European Standard brass alloys such as CW617N (CuZn40Pb2) for standard applications and low-lead variants to meet Swiss SVGW/SSIGE requirements. For potable water, alloys conforming to the 4MS Positive List (like CW724R or lead-free alternatives) are sourced to prevent lead leaching and ensure compliance with strict local regulations.
Yes, all threaded products are machined in compliance with ISO 228-1 (parallel gas threads, often denoted as BSPP) or ISO 7-1 (tapered threads), ensuring direct compatibility with Swiss-manufactured underfloor heating manifolds, boiler circuits, and plumbing unions without cross-threading issues.
Our quality control is governed by our ISO 9001:2015 system. Our quality policy, "Fine work, no leakage," dictates that 100% of finished valves undergo pneumatic testing at 6 bar and mechanical hydraulic testing at 1.5 times nominal pressure rating (e.g., up to 24 bar for a PN16 rated valve) before dispatch.
Yes. Utilizing over 600 sets of advanced machinery—including 80 specialized multi-axis CNC stations—our design team supports ODM and OEM custom forging. We can adjust handle lengths, body weights, wall thicknesses, and connection thread lengths to suit specific Swiss district heating systems or OEM boiler kit integrations.
We work with global freight forwarders to handle shipping from Ningbo/Shanghai ports to European logistics hubs. We provide complete documentation—including Material Test Reports (MTRs), Certificate of Conformity (CoC), and packaging declarations—ensuring seamless customs clearance at Swiss borders.
