Pressure Reducing Valve, Series 300
OVERVIEW
Dorot’s 300 Series, state-of-the-art automatic control valves are designed to withstand the most demanding requirements of water system control. Dorot experts developed this technically advanced valve with capabilities – far beyond any other on the market. The following information will guide and asist you in the selection of the optimal DOROT Series 300 valve.
FEATURES & ADVANTAGES
The capability to regulate near zero flow, as standard on all sizes, eleminates the need for a special low flow (throttling plug) or valve, while ensuring very low head loss in “fully open” position.
• The flange (face-to-face) dimensions suit ISO Standards.
• The valve has an internal floating shaft, allowing for frictionless operation. The unique design of the shaft provides for easy field maintenance.
• The valve has a resilient seal disc, guided by a frictionless centering device.
• The valve’s body is made of Ductile Iron, withstanding both high hydraulic and mechanical stresses.
• The standard single – chamber valve provides smooth operation in sensitive regulation conditions. When required, conversion from a single to a double chambered valve is easily accomplished through the insertion of Dorot’s innovative separation disc, without the need to remove the valve from the pipeline during the conversion.
• The valve is supplied with a replaceable Stainless Steel seat, which maintains excellent durability against erosion and ensures a drip-tight seal.
• During valve closure the rate slows, preventing potential damage from water hammer or surges.
• The 300 Series includes an optional valve position indicator, attached by a floating connection (ball & socket), resulting in smooth movement, with no wear or tear on the indicator seal.
