Electric Double Seat Control Valve Manufacturer in Africa

Product Introduction

Applications involving high flow rates and continuous automatic process control require valves that provide smooth modulation with balanced operating forces. An Electric Double Seat Control Valve combines a double-seat globe valve with an electric actuator to accurately regulate the flow of liquids, gases, steam, and other industrial process media. The balanced double-seat construction reduces the operating force required by the actuator while maintaining stable control under varying pressure conditions. African Valve is a Leading Electric Double Seat Control Valve Manufacturer in Africa, manufacturing and supplying Electric Double Seat Control Valves in various material grades, pressure classes, trim configurations, and electric actuator options for projects across Nigeria, Egypt, South Africa, Kenya, Ghana, and other African countries, along with international export destinations.

Why Is an Electric Double Seat Control Valve Used?

An Electric Double Seat Control Valve is suitable in instances that demand automatic flow control, high flow capacities, and precision positioning. In a situation where there is no need for air supply. The two seats enable the balancing of hydraulic forces working on the valve plug, hence allowing the electric actuator to function effectively under higher pressure differential. This valve is normally mounted in utility services, steam systems, cooling water services, process plants, and power generation facilities.

Design & Working Principle

Components of this valve include globe style housing, upper and lower valves, two seat rings, stem, electric actuator, and intelligent control system. The control system provides an electrical input to the actuator, and this causes the electric motor to rotate the valve stem in order to provide precise positioning. Movement of both valve plugs is synchronized and regulates the flow through upper and lower seats and balances the hydraulic forces inside the valve. This makes it possible to achieve good modulation, high capacity and low actuator loading. Based on the application needs, the valve can have balanced trim, intelligent electric actuator, manual override and other accessories.
