Pneumatic Angle Type High Pressure Regulating Control Valve Manufacturer in Africa

Product Introduction

High pressure process systems demand valves that not only offer precise control but also operate efficiently in harsh environments. A Pneumatic Angle Type High Pressure Regulating Control Valve is specifically designed with an angled body and a pneumatic actuator to control the flow of process fluids such as liquid, gas, steam, etc., at high pressure. An angled flow path in the valve allows it to operate effectively in situations where high pressure differential exists. African Valve is  the largest  Pneumatic Angle Type High Pressure Regulating Control Valves Manufacturer in Africa. It produces and delivers its products in various material grades, pressure classes, and actuator options for projects in Africa as well as international markets.

Why Is a Pneumatic Angle Type High Pressure Regulating Control Valve Used?

Pneumatic Angle Type High Pressure Regulating Control Valves are employed in situations wherein there is a need for precision regulation in high pressure operations where the process might be subject to flashing, cavitation, or high velocity of fluids. The angle body configuration makes it possible for the valve to change the direction of flow while at the same time maintaining a reduction in pressure loss and erosion due to severe conditions of operation. Pneumatic operation allows a quick response to control signals to make it possible to regulate flow, pressure, and temperature without stopping the process.

Design & Working Principle

This valve has an angular body, high-pressure trim, valve plug, seat ring, stem, pneumatic actuator, and intelligent positioner. Once it receives a signal from the controller, the actuator raises the stem up, thus positioning the valve plug inside the seat with precision. Thus, it controls the flow area gradually, ensuring controlled operation of the process fluid regardless of the high pressure differences. As per the needs of the service, the valve comes with pressure balanced trim, multi-stage pressure reducing trim, cavitation control cages, low noise trim, and intelligent positioners.
