A Silent Check Valve Is A Valuable Tool
A globe style silent check valve is also a variation of cam-style valve used to regulate flow in a hydraulic system, consisting of a rotating disk-like element and a fixed ring seat on a generally rectangular body.

As the name implies, globe style valve bodies are circular and are employed for restricting hydraulic fluid through a series of needle holes that are located in various places around the inner surface of the disk. This type of valve also has an adjustable outer ring seal that lets excess water escape while preventing pressure from building up. The primary advantage of this style valve body is that it requires fewer seals than conventional types. However, this style also allows more control over the amount of hydraulic flow, and it does not have the ability to overcome higher temperatures.
A silent check valve disc is used in conjunction with a spring loaded seat. In this configuration, the spring is located within a housing, such as a cylinder or a sleeve, and the valve disc is placed inside the valve body so that the spring can be pivotally controlled via a small lever that pulls out the reverse direction of the spring. The amount of hydraulic flow is controlled by means of a reversing lever on the top of the disc. The housing serves to keep the spring compressed and to protect the seat and the piston arms.
There are four primary ways in which a silent check valve prior to maximum water hammer will operate. First, the piston will move up when the seat pushes against the spring. Second, the piston will move down when the seat moves away from the spring. Thirdly, the spring will continue to force the piston upward, thereby allowing fluid flow reversal to occur.
The four types of operation modes are illustrated in figure two. The first mode is referred to as the return position. In this situation, the pressure of the hydraulic fluid that has been injected into the system remains constant. This mode is used most often when a sudden increase in hydraulic pressure occurs, such as when the piston reaches the top of its movement in the case of an oil drum or when the hydraulic fluid reaches its boiling point. In such cases, the valve remains in the closed position because there is no pressure increase.
The second mode, known as the flow check valve, occurs when the hydraulic fluid changes direction. When this occurs, the valve is moved into the "on" position. This condition allows for the escape of some of the fluid oil, and therefore does not cause a pressure increase. In spite of this advantage, many manufacturers have designed silent check valves that remain in the open or "open" position when there is flow. These valves have additional benefits, namely the ability to prevent the valve from becoming obstructed by splashed water and oil.
The third type is called the water hammer valve and is used when there is high or irregular water flow. For example, the controlled flow check valve can be employed with high water flow, but because of its design it will remain in the closed position when there is very little or no water flow. The water hammer control valve, on the other hand, will start to leak when there is a considerable amount of water flow. The water hammer control valve is designed to counter the excessive pumping of water out of the tank that causes water pressure fluctuations. This type of valve also has a number of additional features, including an adjustable safety stop, a manual shut off control, an indicator light, and a variable-speed drive.
