fe05ad77-69a2-5513-9fc2-cb845a0772d0Frese Hydronic Control and Balancing Valve (Ductile (cast) iron)MaterialBuilding TechnologyHVACProduct description:
The Frese control and balancing valve range in this EPD consists of large-dimension hydronic valves used to keep water-based heating and cooling systems stable, predictable and energy efficient in buildings and district networks. The product group covers pressure independent control valves of the OPTIMA Compact Veriflow series DN50–DN300, SIGMA Compact dynamic flow-limiting valves DN50–DN300 and PV Compact differential pressure control valves DN40–DN200, ALPHA Wafer DN50-DN1000 and OMEGA Compact DN65-DN800. Together, these valves help maintain design flows and stable differential pressures in mains, risers and branches so that downstream control valves, coils and heat exchangers can work with good authority and low risk of noise, even when pump speed and system load are changing.
Within the product group, the pressure independent control valves combine an externally adjustable automatic balancing function, an integrated differential pressure controller and a full-authority modulating control section in a single body, providing dynamic flow and temperature control without the need for separate balancing valves. The dynamic flow-limiting valves provide externally adjustable, constant flow limitation and isolation to different parts of the system, so overflows and unnecessary pump energy are avoided while still allowing measurement and verification via integrated test points. The differential pressure control valves are installed typically in the return line and keep the pressure difference across a circuit or group of valves at a set level, creating stable conditions for modulating control valves and reducing the risk of hydronic noise.
Across the range, the valves consist of cast iron or ductile iron bodies with internal components such as stainless-steel springs, diaphragms and cartridges, complemented by elastomeric sealing elements like EPDM O-rings and diaphragms designed for typical HVAC pressures and temperatures. In many applications these valves are used together with electric actuators, capillary tubes and external controllers, but in this Environmental Product Declaration only the passive mechanical valve assemblies, including integrated measuring points, are included in the assessed product system; actuators and other external control equipment are not part of the EPD scope.
Physical properties of the product:
Materials: The valves in this group are primarily made of ductile/cast iron GJS 400-18RT, accounting for more than 80% of their total weight. Other materials include stainless steel, steel, brass, copper, zinc, rubber (EPDM), and different types of plastic (such as ABS, PPS, PTFE, SEPS and PE-LD).
