Is a ball valve the same as a check valve?
Ball check valves should not be confused with ball valves, which is a different type of valve in which a ball acts as a controllable rotor to stop or direct flow. A diaphragm check valve uses a flexing rubber diaphragm positioned to create a normally-closed valve.
Do check valves come in different sizes?
As simple as this logic is, check valve sizing is largely misunderstood. Check valve “sizing” refers to how much the valve’s disc opens in order to accommodate media flow through a pipe – a vital component to the system’s overall functionality.
Does a check valve go before or after a pump?
The check valve must be installed at the outlet of the pump and in front of the outlet control valve for maintenance. Generally, the first outlet of the pump is the soft connection (shock absorber), the next is the check valve, and then the block valve.
How do I choose a check valve?
Some of the things you may need to consider are fluid compatibility, flow characteristics, headloss, non-slam characteristics and total cost of ownership. For optimal performance, it is of course important to choose your valve respecting the characteristics of each specific installation.
What is a ball valve used for?
For use in general purpose applications with water, oil, and inert gas. The three -piece bolted body comes apart for access to internal components without unthreading pipe connections and removing the valve from your line. Also known as actuated ball valves, these provide higher flow rates than other air-driven valves.
What is a wafer ball valve?
Also known as wafer ball valves, these combine the slim body of a butterfly valve with the high flow rates of a flanged ball valve. They bolt to ANSI flanges.
What is the difference between solenoid and proportional V-Ball valves?
Also known as proportional V-ball valves, these have a motor that adjusts and regulates flow in applications with higher flow rates and pressures than solenoid valves. As you increase the intensity of the electrical signal, the motor opens the valve, moving a ball with a V-cut opening that proportionately allows more flow as the valve opens.
How do you use a pressure gauge valve?
Use these valves in general purpose applications with water, oil, air, inert gas, and steam. Extend your reach in hard-to-access areas— turn these valves on and off using a square ratchet to grasp the hole at the end of the handle. Use with water, oil, air, and inert gas. Attach a pressure gauge to the side port on these valves.
