OKE Control Valve Working Principle

The working principle of the American OKE control valve mainly includes the throttling principle, pressure regulation principle, and temperature regulation principle. The throttling principle involves changing the flow area between the valve core and the valve seat to achieve throttling of the fluid. The pressure regulation principle controls industrial processes by altering the fluid pressure. The temperature regulation principle controls industrial processes by changing the fluid temperature.

OKE Control Valve Overview

A control valve is an important industrial control device primarily used to regulate process parameters such as fluid flow, pressure, temperature, and liquid level. The main components of a control valve include the valve body, valve core, valve seat, valve stem, and stuffing box. Among these, the valve body is the main part of the control valve, typically made of materials such as cast iron or cast steel; the valve core is the core component of the control valve, connected to the valve seat via the valve stem, allowing it to move up and down or rotate; the valve seat is the inlet and outlet of the control valve, usually made of corrosion-resistant materials; the stuffing box is the sealing component of the control valve, used to prevent fluid leakage.

OKE Control Valve Features

The American OKE (OKE) imported top-bottom, double-guided double-seat control valve offers excellent stability during operation.

It features two valve cores and valve seats, with a "four-way" valve body design, allowing easy conversion from direct to reverse installation, and from air-to-close to air-to-open operation.

The valve body is designed based on fluid dynamics principles, featuring an equal cross-section, low-flow resistance flow path with a high rated flow coefficient.

It has low unbalanced force, allowing for a larger allowable pressure difference.

The actuator adopts a multi-spring structure, reducing height by 30% and weight by 30%.

It offers a wide adjustable range, with an inherent adjustable ratio of 50%.

The bellows-sealed control valve provides complete sealing for the moving valve stem.

The control valve is equipped with an insulation jacket, suitable for applications where fluids are prone to crystallization, solidification, and blockage after cooling.
