gate valves

The body of valves is made by advanced castiron, which is lighter than normal gate valves about 20%to 30%, and easy to install and maintain.

DO NOT use valves that may cause excessive restriction to water flow. Use full flow ball or gate valves only.

Bypass valves , if required, shall be gate valves of the same size as the main line.

Gate valves shall be suitable for cold potable water and shall be design for operation with hand-wheel.

Conduit valves are a form of gate valves with elongated gates.

KVTs' SPL parallel slide gate valves can be flow throttling in any form of flowing condition.

Virtually no contamination of the environment. No dewatering of stock, unlike standard knife gate valves.

(THROTTLING FACTORS) For throttling use with disc partially open. Multiply Cv by factor. NOTE: Gate valves are not throttled.

The proper method for draining both Y-pattern stop-check valves and isolation gate valves is shown for typical mounting positions.

Note that stem load is applicable to gate valves only as this force is included in the seating force of globe and stop-check valves .

Knife Gate valves should preferably not be opened or closed against pressure.

The fuel tank balance pipes and gate valves should all be inspected every year to check for any deterioration .

Gate valves are normally installed in horizontal pipe runs with the valve stem vertically up.

Typical NACE material configurations are shown below for Crane cast steel gate valves.

NO CAVITY There is no cavity ( similar to Gate Valves ) to allow build- up of solids .

All gate valves should be market according to the relevant specification standard.
