What is a foot control valve?
Foot control valves allow operators to control the high-pressure water flow. PSI offers foot control valves rated for 15,000 psi (1,034 bar), 20,000 psi (1,400 bar), and 40,000 psi (2,800 bar). Traditional dump- style and dry-shut off models are available.
What is the benefit of a foot switch?
Benefits of using Footswitches · They are space saving as they are on the floor and off the work desk. · Footswitches are more hygienic than hand controls as they are not passed from person to person. · They also offer hands free operation so the user can multitask.
When would you use a foot valve?
Use foot valves when you have situations that need a pump, such as when water needs to be extracted from an underground well. Foot valves keep the pump primed, allowing water to flow in, but not letting it flow back out, making them ideal for use in pools, ponds, and wells.
How does a foot switch work?
Pneumatic footswitches work in the same way as pneumatic push button switches but are operated by the foot. Rather than an electrical connection, when a pneumatic footswitch is compressed, a puff of air is sent down a length of PVC tubing. This actuates an air switch which is connected to an electric circuit.
What is a PC foot pedal?
The USB foot switch can be used to control your computer by foot. It is used in playing games, factory testing, controlling instruments, helping the disabled and so on. You can use it by hands or feet for efficiency. The number or style of pedals can be customized according to customer’s request.
What is a foot pedal?
Definitions of foot pedal. a lever that is operated with the foot. synonyms: foot lever, pedal, treadle.
Do you need a foot valve?
Why Are Foot Valves Needed? Foot valves are beneficial because they prevent damage to water pumps that can occur due to dry runs, as well as stopping wastage of energy. These valves are a necessary part of all water pumping systems.
Where do you put a foot valve?
The foot valve is required to be installed at the bottom of the well suction line piping. Similar to the check valve, the foot valve prevents water from flowing back out of the jet pump. This protects against loss of prime in the well piping system.
Can a foot valve get clogged?
A clogged foot valve could be reducing the rate at which the pump can pick up water from the lake. A worn, damaged, or debris-blocked impeller in the pump itself could be the trouble as could an air leak at the pump (do you see bubbles in the output water?)
How do I choose a solenoid valve?
To determine the optimal size for your solenoid valve, you need to know the flow rate, which allows you to determine the flow factor (kv). The flow factor is a theoretical value that indicates the volume of water at room temperature that flows through the solenoid valve with a pressure drop of 1 bar for one minute.
Why is it called a 3 2 valve?
A 3/2-way valve has three ports and two positions that can be driven pneumatically, mechanically, manually or electrically via a solenoid valve. They are used, for example, to control a single-action cylinder, driving pneumatic actuators, blow-off, pressure release and vacuum applications.
