What are the various types of ball valves

 A reduced port Ball Valve, also commonly referred to as a standard port valve, has the internal diameter of one pipe size lower.It is especially important to understand this concept when valves get much larger in diameter. There can be significant cost savings derived from going with a reduced ported valve if the application allows you to do so. As you can well imagine, an 8” reduced port valve, which has the internal diameter of a 6” pipe, will be significantly less expensive than an 8” full port valve.

In addition to the aforementioned differences in porting, ball valves also come in one-piece, two-piece, and three-piece configurations. All these styles would be available with either full or reduced ports. A three-piece valve, just as the name implies, has three main pieces that make up the valve: a center section and two end sections. The center section houses the ball, stem, and valve seats. The two end sections provide the piping connections and are typically offered in threaded, socket weld, or butt weld options. These end connections can be removed from the valve’s center section and independently installed into the piping system.

These end connections act like a union, otherwise known as a ground joint union. These unions, or end pieces, on a three-piece valve enable the pipe fitter to install the valve in the piping system at the point of service. Three-piece ball valves are usually more expensive than one or two-piece ball valves. However, when using one or two-piece valves, you must still budget for the installation of unions upstream and downstream of the valves themselves. Often, the additional costs for unions and the labor to install them outweigh the incremental increase in price when using a three-piece valve.

Also, when evaluating the overall cost of an installed valve, things like unions and required pressure ratings can weigh heavily on the bottom line. rated valve will cost far less than a rated valve.It’s important to consider these aspects of your application prior to choosing or specifying a particular valve.Finally, another cost consideration when making your selections is whether you will be automating any of the valves that will be installed. If automation remains a possibility in your future plans, you should seriously consider opting for a valve with an actuator mounting pad for ease of this automation. An international standard has been created for this purpose compliance defines a set of standardized mounting dimensions which all manufacturers of ball valves must employ for ease of mixing and matching actuation packages.

How Does A Floating Piston Valve Work

 Floating piston valves as used in, have Check Valve several applications. Floating piston valves have a very unique construction. Composed without an actuator and designed with less parts, floating piston valves require less maintenance, reducing their size and cost. Newer models of the floating piston are of higher quality, addressing pre-existing issues from previous designs.A floating piston valve consists of a solid piston pressed against a stationary, solid seat that is suspended in a medi in order for it to control the flow stream and seal the valve.

Whether the valve is open or closed, floating pistons are specifically designed to remain balanced within a flow stream. The only force used on a piston is that which the operator chooses to input. Because of the requirement to use this valve manually, there is the eliminated factor of an actuator and in its place is one to two solenoid valves.The floating piston is a rather simplistic valve, composed of only five parts, with its seals manufactured to be well-protected by design.

The floating piston valve’s simple design makes it a durable option for high pressures, soft or hard metal seats, while increasing the valve’s reliability and seat life. By eliminating the actuator, the valve’s dependability and lifespan are greatly improved. Its structure is specifically manufactured to ensure that fluid pressures inside of the valve will remain balanced, giving the floating piston valve an increased lifespan.

Piston Valves have a wide variety of potential applications and are fairly versatile. Its simple design makes it reliable and easy to maintain.Over the years floating piston valves have been re-engineered to enhance the stability of the design to ensure its stability. New models are compatible with hard or soft metal seats with an adjustable closing force. Some newer floating piston valves are able to withstand pressures up to.
