DeZURIKMS I DeZURIK BALANCING VALVES Design & Construction The DeZURIK Balancing Valve is designed specifically for heating/air conditioning systems in multi-story commercial buildings. Balancing valves provide a means of adjusting and reading the flow in condenser and hot or chilled water systems. These valves help maintain the desired flow, balance point and temperature throughout the building. The resilient faced plug provides balancing and positive shutoff capabilities in one valve. Balancing valves are available in 1-24" (25-600mm) sizes. Smaller sizes on application. Flow curves are available that represent valve characteristics by individual valve size, providing an accurate means for balancing and measuring flow in the system. Flow Taps All valves are available with upstream and downstream flow taps, allowing easy flow measurement and optimum valve positioning. Fittings consist of two 1/8" (3mm) N.PT. air valves with sealing caps or two 1/8" (3mm) petcocks with quick disconnect couplings. High Flow Capacity The clean interior design and straight-through flow pattern allow high maximum flow capacity with minimal pressure drop. Bolted Bonnet All valves have bolted bonnet construction, allowing easy disassembly if maintenance is required. Dual Bearings Each valve has stainless steel bearings in the bonnet and body to prevent binding and to assure lasting, easy valve operation. Dead-Tight Shutoff Resilient plug facings provide dead-tight shutoff without the use of sealing lubricants. The standard resilient plug facing provided is CIIR, Chloro-Isobutene-Isoprene, with a maximum temperature rating of 250°F (121°C). Other compounds are available on application. Wide Choice of Body Materials DeZURIK offers a wide choice of body materials to meet your individual application requirements.
