Linear flow ball valve
PlastOMatics Series ZC Characterized Ball Valves with Linear control will save you money in five important areas: The Series ZCs new linear profile provides precise control over a longer control range which allows for accurate chemical dosing control. This means you save money on chemical usage!Feb 26, 2015 In a linear (constant gain) valve, a 1 change in lift results in a 1 change in flow (Gv 1. 0). TPG is acceptable if it stays between 0. 5 to 2. 0, as the load varies between its minimum and maximum limits. Linear valves are used in most applications except heat transfer (temperature control). TPG (Gp)(Gs)(Gv) 0. 5 to 2. 0 linear flow ball valve
The majority of control applications are with valves with linear, equalpercentage, or modifiedflow characteristics. Installed Control Valve Flow Characteristics. When valves are installed with pumps, piping and fittings, and other process equipment, the pressure drop across the valve will vary as the plug moves through its travel.
Product Description, Dimensions and Specifications PDF. Series VP1000 (Stainless Steel VPort Ball Valve) VBall and VPort ball valves are an ideal solution to control flow through a pipe. VBall valves are a great solution to modulate flow and can be actuated. This series of VBalls are made from 316 stainless steel and are configurable in almost any industry. Globe valves use linear actuation and have been the preferred type of control valve for decades. While they offer more precise control due to a more linear flow curve (Figure 3) and do not suffer the uneven wear in the mid positions, they do not typically provide a bubble tight shutoff. The flow path in VPort ball valves produce a much linear flow ball valve Mar 08, 2017 A ball valve is typically a quarterturn valve with a perforated ball in the middle to control flow. These valves are known for being durable with excellent shutoff, but dont always offer very precise control. Lets talk about when its okay to use a ball valve as a control valve.
Linear Control Valves Ideal for highaccuracy flow regulation, the Flowserve family of globeangle linear control valves can be applied from general service to severe applications for both gas and liquids. They are ideal for frequent operation due to their excellent position accuracy and repeatability. linear flow ball valve In fact, most globe control valve designs can be changed from linear to equal percentage (and vice versa) by changing the trim. The ball valves (both full ball and segmented ball) exhibit a nearly perfect (more so than most equal percentage globe valves) equal percentage inherent characteristic. Oct 20, 2015 The linearstyle valve is the most common type of valve available today. It is wellknown for its simple design and ease of maintenance. Linear valves, also known as multiturn valves, have a slidingstem design that pushes a closure element into an open or closed position. Standard Linear Flow Cuts are used to provide a predetermined flow rate based on the angle of opening. Flow rate increases on a linear curve as the valve is opened. The G2 Linear Flow Valve allows you to easily fine tune your flow rate for sparging, lautering and chilling, increasing the repeatability of your system. The built in 90 degree outlet can be oriented at any angle to make hose routing simple and kinkfree. Eliminate those extra elbows and other fittings on the valve for clean and simple routing.Rating: 4.45 / Views: 501
