Electric angle seat regulating valve
Electric angle seat regulating valve
Product details
ZDLS electric angle regulating valveDDZIt consists of two parts: a straight stroke valve and an angle valve. Using single-phase communication220VPowered by electricity, accepting0～10perhapsmAperhaps4～20mADC signal automatically controls the opening of the regulating valve to achieve continuous adjustment of process parameters such as pressure, flow rate, temperature, and liquid level of the fluid in the pipeline.
1ZDLSOverview of Electric Angle Regulating Valve
Electric angle regulating valveSmall in size, light in weight, with a top guide structure for the valve core, it has the characteristics of simple flow path, low resistance, and easy flushing.
Suitable for regulating media with high viscosity, suspended solids, and granular media that require right angle connections.
