ZDLM Electric Sleeve Control Valve

ZDLM - Electric sleeve control valve

Advantage: good stability, large flow, simple maintenance, small size and light weight.

Application: Single seal type - used to clean medium with strict leakage requirement, low pressure difference. It can be used as shut-off valve through upgrading

Double seal type - used to clean medium with low leakage requirement, large pressure difference.

Throttling type - used to be as low noise valve
