What is the best flow control?
For flow control applications where a ball valve is possible, such as filling a tank to a reasonable degree of accuracy, a trunnion or v-port ball valve design is usually the best choice.
What is the function of flow controller?
Liquid flow controllers can be used to measure and control flow rates of various types of liquid-based samples. Liquid flow controllers will typically be used in applications that require a constant flow rate and can compensate for varying pressure changes.
What is a rate of flow controller?
Rate of flow control valves are automatic control valves that are designed to limit flow rate to an adjustable maximum. The factory calibrated orifice plate can be installed downstream or upstream. Feature combinations include pressure reducing, pressure sustaining, hydraulic check, or solenoid (on-off).
How does a boiler flow control valve work?
Flow check valves are controls that prevent hot or chilled water from circulating in the heating or cooling system at certain times. We offer flow check valves (or boiler check valves) that provide positive shutoff when the circulator is not running, preventing the flow of water to radiation units.
What is a level controller?
Level controllers monitor, regulate, and control liquid or solid levels in a process. Level controllers receive input from a level-sensing device and respond accordingly based on the device and user specifications.
Do I need a backflow preventer on my boiler?
Why do we need a Backflow Prevention Device on Heating Boilers? Because a building potable water supply piping cold water line is used to deliver water to hydronic or steam heating boilers, we need to prevent heating system water from back-contaminating the building water supply piping.
Can butterfly valves be used for throttling?
Unlike gate valves, butterfly valves can be used for throttling or regulating flow as well as in the full open and fully closed position. The pressure loss through a butterfly valve is small in comparison with the gate valve.
What is a constaflo water flow controller?
Parker Bestobell’s Constaflo is a simple but effective water flow controller that ensures flow rates are maintained within +10% of its rated capacity, regardless of upstream or downstream pressures.
What is an adjustable rate flow control valve?
Rate of flow control valves are automatic control valves that are designed to limit flow rate to an adjustable maximum. The factory calibrated orifice plate can be installed downstream or upstream. Feature combinations include pressure reducing, pressure sustaining, hydraulic check, or solenoid (on-off).
What is Plumbing&Flow Control?
An extensive range of plumbing and flow-control products. All designed to facilitate efficient water conveyance and control for commercial, residential, and industrial applications. You need it. We make it. Let’s get started.
What is an automatic water pressure control valve?
We offer automatic control valves that are used to ensure uninterrupted water service during emergencies, maintain a constant liquid level in tanks, automatically reduce a higher upstream water pressure to a constant downstream pressure, and for other purposes.
