Control Valves

Control Valves

REGPORT is renown as a specialist in the field of Pressure Regulators and Pressure Relief Valves. Recently, we have expanded our product range and based on our experience and extensive international exposure across the different industrial segments, we have ventured a complete range of Control Valves including 2-way Control Valves. 3-way Control Valves, Butterfly type Control Valves and On/Off Valves.
Applications range from the most simple to the most severe conditions like high pressure drop, noise reduction, low temperatures, corrosive services, liquids with abrasive elements and many more.
REGPORT is committed to have the most reliable and commercially acceptable Control Valves with the apex importance to the technical correctness.
RC1000 is designed to ensure it represents a cost effective solution to a variety of process control applications, the RC1000 range is limited to a core of options, which allow rapid delivery, high interchangeability of trims and lower costs.
A control valve is An instrument used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level.

On/Off Valve

Different Flow Characteristics

  • Quick – Opening Characteristic : This trim profile provides the maximum change in flow rate at low valve travels. In a control valve the quick – opening characteristic is used primarily for on-off service, where the flow must be established quickly as the valve begins to open.

  • Linear Flow Characteristic : The linear flow characteristic curve shows that the flow rate is directly proportional to valve travel. This proportional relationship produces a characteristic with a constant slope, so that with constant pressure drop, the valve gain is the same at all flow values. The linear characteristic valve is commonly specified for liquid level control and for some flow control applications.

  • Equal Percentage Characteristic : This characteristic produces flow changes which are equal percentages of the existing flow, for equal increments of valve travel. The change in flowrate is always proportional to the flow rate that exists just before the change in valve position is made, this means a given change in valve travel always produces the same equal percentage change in existing flow. These are probably the most frequently specified, for pressure control as it is considered their particular gain characteristics are the most tolerant and are likely to provide stable control at low lifts.
