Whether you are a professional in the valve industry or simply curious about valve technology, this article will provide you with valuable insights. So, let’s dive in!

Introduction

Motor operated valves (MOVs) are essential devices used to control the flow of various fluids in industrial processes. These valves are commonly found in industries such as oil and gas, power generation, water treatment, and chemical processing. Rotork, a renowned manufacturer of valve automation solutions, offers a wide range of motor operated valves that excel in performance, reliability, and durability.

Understanding Motor Operated Valves (MOVs)

Motor operated valves, as the name suggests, are valves that utilize an electric motor to open, close, or modulate the flow of fluids. These valves are designed to automate the control process, eliminating the need for manual operation. By incorporating electric motors, MOVs can be remotely controlled, allowing for precise and efficient flow regulation.

Components of Rotork Motor Operated Valves

Rotork motor operated valves consist of several key components that work together to ensure proper valve operation. These components include:

1. Actuator

The actuator serves as the heart of the motor operated valve. It houses the electric motor, gearbox, and other mechanical parts necessary for the valve’s movement. Rotork actuators are known for their robust construction and reliable performance.

2. Valve Body

The valve body provides the passage for fluid flow and houses the internal valve mechanism. It is typically made of durable materials such as stainless steel or cast iron, depending on the application requirements.

3. Control System

The control system is responsible for receiving signals and commands to control the valve’s operation. It includes a variety of components such as sensors, controllers, and communication interfaces.

4. Positioner

The positioner is a crucial component that ensures the valve reaches the desired position accurately. It receives signals from the control system and adjusts the actuator’s position accordingly.

Working Principle of Rotork Motor Operated Valves

Rotork motor operated valves operate based on the principle of linear or rotary motion. When the control system sends a signal to open or close the valve, the actuator converts this signal into mechanical energy through the electric motor and gearbox. This energy is then transferred to the valve mechanism, causing the valve to move accordingly.

Applications of Rotork Motor Operated Valves

Rotork motor operated valves find extensive applications across various industries. Some common areas where these valves are used include:

Oil and gas pipelines
Power plants
Water and wastewater treatment facilities
Chemical processing plants
Pharmaceutical industries
Food and beverage production
