Automatic recirculation pump protection valves are used to protect the pump minimum flow
Automatic recirculation pump protection valve are used to protect the pump minimum flow
automatic recirculation valve for the protection of the centrifugal pump to prevent pump damage caused due to overheating, excessive noise, instability and cavitation at low flow conditions.
Depending on the main flow, the recirculation valve of the main valve disc will be determined in a certain position, the check valve stem of the main road through a lever, the main valve motion is passed to the bypass, the bypass system control through nextroad traffic and the pressure reduced to export the desired value, when the main valve back seat off all flow through the bypass (back), rises to the top position when the main valve, the bypass is completely shut down all pumpstraffic flow of process systems.
Connection Flange standards and other standards according to DIN or ANSI flanges, such as: ISO, BS, JIS, NF, available on request. The connection of the import and export of welding can be used. Bypass connection using only the flange connection (easy to check). Material
Standard body material: W. -Nr.1.0460 (C22.8) (ASTMA105).
TDC the valve’s internal parts and materials, the standard product for a minimum chromium content of not less than 13% of stainless steel. Control sleeve, the sleeve seat and vortex cone surface treatment (ion vacuum quenching) to wear resistance.
Other for the body and internal parts of the forging material is available on request.
The choice of body material, determined in accordance with the conditions of pressure and temperature.
