TALIS Control valve. State-of-the-art automatic control valves are designed to withstand the most demanding requirements of water system control. Talis experts developed this technically advanced valve with capabilities - far beyond any other on the market. The following information will guide and assist you in the selection of the optimal Automatic Control valve Hydrobloc.
Valves
The handy Valve Catalogue is split into five sections to showcase the different types of valves available, the catalogue features a wide selection of butterfly and gate valves, non return valves, control valves and miscellaneous ones.
For each valve on offer, the catalogue provides detailed product information, as well as data on the valve’s key features and benefits. It also clearly lists the advantages of each valve so that customers can determine whether it would be suitable for their particular needs and how it will benefit certain jobs.
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.
