300 Series

300 Series

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

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.
