Check valve with manual bypass

 · This video is about Hydraulic Bypass check valves in fluid power circuit. It will hopefully help you to understand how and when to use a bypass check valve. The subject of valve types is addressed in Types of Valves and Their Applications.. Trap with Built-in Bypass Valve. There is a model of steam trap that has a built-in bypass valve. To use this trap, at start-up open the bypass valve to rapidly discharge the start-up condensate. NFPA 58). This manual must be kept with the bypass valves and be reviewed before installing, operating or performing any maintenance work. Warning! Do not attempt to open the pump or bypass valve until you have bled off the pressure. High pressure in the system can cause personal injury and/or property damage.

Clover's resilient seated integral bypass gate valves comply with AS for pipeline isolation use in above and below ground pressure water supply and sewerage applications. Clover's integral bypass gate valve provides a compact footprint through faster installation and reduced installation costs. Size chart and ratings. The bypass unit adjuster consists of a lock nut, adjusting screw, plunger, and check valve. When oil is passed thru the bypass tube, the check valve is pushed back against the plunger, whose depth is determined by the adjusting screw. With the valve in the open position, oil can bypass the piston, the greater the distance between the plunger. The most common bypass systems are the Autotrol® Series bypass valve (Figure 4) and plumbed-in globe valves (Figure 5). Though both are similar in function, the Autotrol bypass offers simplicity and ease of operation.

Bypass piping can roughly be divided into two categories. Bypass piping that acts as a backup line to allow operation to continue while damaged equipment such as pressure reducing valves and steam traps are isolated and shutdown during replacement or repair. Bypass piping whose purpose is to supplement the performance of pressure reducing. The Equilibar precision back pressure regulator can provide pump bypass pressure control by using an air setpoint signal provided by a manual or electronic pressure regulator. This larger 2″ Equilibar® pressure bypass valve can be piloted manually or electronically to provide accurate pump pressure control. NFPA 58). This manual must be kept with the bypass valves and be reviewed before installing, operating or performing any maintenance work. Warning! Do not attempt to open the pump or bypass valve until you have bled off the pressure. High pressure in the system can cause personal injury and/or property damage.
