Water Control Valves flow coefficient C v diagram The flow coefficient C v for a water control valve can be estimated with the diagram below: Example Required C v for a water control valve. With water flow 6 gpm and designed pressure drop 10 psi through a control valve the required flow coefficient C v can be estimated to ~ 2 as indicated in the chart below. A Check Valve Is Required For A Water Well. Conditions Controlled by Your Check Valve. Along with holding water pressure in your system, your check valve assists in the smooth and safe operation of your water system by extending its life and preventing backspin, up thrust and water hammer. Here are a few conditions check valves help to control. Backspin Types of Water Shutoff Valves The internal ball has a hole through the center of it. When the valve is open, the hole is aligned with the direction of the water pipe, allowing water flow. When the handle is closed, the ball rotates 90° so the hole in the ball is blocked. This is quite a common type of valve on main water pipes. Water System Backflow Preventers & Check Valves DIY repairs On a well and pump water supply system a check valve may be installed between the incoming water line from the well and the water pump and pressure tank, such as shown in this photograph of a one line jet pump with a check valve right at the water pump inlet. Check Valve Diagram | Products & Suppliers | Engineering360 Description: included check valve should be installed in the return line downstream from the Return manifold to prevent backflow to the mold. Tubing may be connected to the manual vent drain port so any residual water after the purge cycle can be drained into a suitable container or floor drain. Understanding Check Valves: Sizing for the Application ... The disc in some check valves extends into the pipeline when the valves are fully open. This could interfere with the performance of another valve bolted directly to the check valve. If possible, install the check valve a minimum of five pipe diameters downstream of any fitting that could cause turbulence. Notice the phrase “if possible.” Baker Water Systems Well Diagram CHECK VALVE (Section G) On pump installations, a Check Valve installed near the tank inlet holds water in the tank when the pump is idle. TANK TEE (Section O) Connects water line from pump to pressure tank and service line from tank to house. Taps are provided to accept Pressure Switch, Pressure Gauge, Drain Valve, Relief Valve, Snifter Valve, etc. Check Valves Valves The Home Depot Brass Check Valve. This check valve keeps prime in jet submersible This check valve keeps prime in jet submersible and centrifugal pump systems. When a pump shuts off the check valve closes preventing the water from back flowing. Long lasting spring loaded check valves are manufactured with high quality brass. Types of Under Sink Shutoff Valves Angle stop valves are normally used when the water line comes out from the wall and the outlet side of the valve will be perpendicular to the inlet side. The handle of an angle stop valve will be parallel to the wall and usually faces the front for easy access. Three way stop valves have an inlet and two outlets. Check valve A lift check valve is a check valve in which the disc, sometimes called a lift, can be lifted up off its seat by higher pressure of inlet or upstream fluid to allow flow to the outlet or downstream side. A guide keeps motion of the disc on a vertical line, so the valve can later reseat properly. Thermostatic Mixing Valves Multicycle Thermostatic mixing valves must have integrated check valves. Thermostatic mixing valves must allow easy cleaning and disinfection operation. Dismantle and clean hoses, taps, showerheads and thermostatic mixing valves minimum once a year. Hot and cold water distribution pipes must be insulated sufficiently (never together). Submersible Pump Check Valves Installation Instructions ... Submersible Pump Check Valves Installation Instructions Models 80 & 100’s 1” thru 12” (See separate O&M for Series VFD valves) Flomatic Corporation Flomatic Valves, 15 Pruyn’s Island, Glens Falls, New York 12801 Valve Although traditionally disc shaped, discs come in various shapes. Depending on the type of valve, a disc can move linearly inside a valve, or rotate on the stem (as in a butterfly valve), or rotate on a hinge or trunnion (as in a check valve). A ball is a round valve member with one or more paths between ports passing through it. By rotating the ball, flow can be directed between different ports. How Do Irrigation Valves Work?

Stan, the check valve on the pressure side would prevent the shore water flowing back thru the pump into the fresh water, but when you are on the pump (no shore water) and the pump residual pressure leaks passed the check valve and drains back into the fresh water tank, causing pump cycling like you had a external leak. Understanding and Using RV Water Systems The sinks will have a check valve by the p trap, looks like a round box sticking off to the side, or it is vented through the roof. These check valves can go bad but not from high water pressure since the water doesn’t flow through it, just air. If you have a check valve on the plumbing near the trap unscrew it and see if the sinks drain better.
