This valve gives installers precise control over water temperature by blending hot and cold water streams into a single mixed output. It is a go-to component for radiant floor heating, domestic hot water systems, and other applications where consistent temperature control is critical to system performance and occupant safety. Viega ProPress fittings are well known in the trade for their tool-pressed, flame-free connections that reduce installation time and labor costs significantly compared to traditional soldering methods. The 87430 fits directly into any ProPress compatible system, making it a natural choice for HVAC technicians, pipefitters, and plumbing contractors who work with press technology daily. The valve body is constructed from brass, which offers excellent corrosion resistance and long service life in potable water and hydronic applications. The press connection components are made from silicon bronze, a material chosen for its strength and compatibility with copper tubing. The seals are EPDM, which is a standard elastomer for water service and performs reliably across a wide temperature range. At 1 inch nominal size, this valve handles the flow demands of residential and light commercial systems. The overall length of the valve is 7.62 inches, with a height of 6.080 inches and a port dimension of 5.81 inches, making it compact enough for tight mechanical room installations. Plumbers and HVAC pros working on energy-efficient hydronic systems will find the Viega 87430 a dependable, code-compliant choice that integrates seamlessly with existing ProPress infrastructure.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePress-fit, flame-free installation using standard Viega ProPress tooling for faster, safer connections\u003c\/li\u003e\n\u003cli\u003eBrass body with silicon bronze press components and EPDM seals for long-term durability in water systems\u003c\/li\u003e\n\u003cli\u003e1 inch size suitable for residential and light commercial hydronic heating and domestic hot water applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe Viega 87430 ProPress 3 Way Mixing Valve delivers reliable temperature blending and quick press-fit installation in a compact, durable brass body.
