Who owns Val-Matic?
A.Y. McDonald Industries
In 2020, Val-Matic was acquired by A.Y. McDonald Industries, a family-owned corporation and manufacturer of products for the waterworks and gas industries.
What is the function of air release valve?
Air Release Valves, or Air Relief Valve function to release air pockets that collect at each high point of a full pressured pipeline. An air release valve can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure.
What is a silent check valve?
Silent check valves, also known as non-slam check valves and spring-assisted check valves reduce or eliminate water hammer and its effects. Water hammer refers to the high-pressure shock waves that occur when the flow of fluid abruptly stops (due to pump shut down or a valve disc quickly closing) in a piping system.
Where do you put air release valves?
Proper installation is critical to the operation of air release valves. Because these valves are designed to release air from the piping system, they should be placed where the air is most likely to collect. Install them at system high points in the vertical position with the inlet down.
What does a gate valve do?
A gate valve is generally used to completely shut off fluid flow or, in the fully open position, provide full flow in a pipeline. Thus it is used either in the fully closed or fully open positions. A gate valve consists of a valve body, seat and disc, a spindle, gland, and a wheel for operating the valve.
What is a singer valve?
Singer Valve designs and manufactures automatic control valves, offering engineered products for pressure management within water works. It also manufactures similar valves used in industrial, commercial and fire protection applications.
When should a air relief valve be installed?
An air release valve is needed to relieve air during system operation. 1. When the flow velocity is greater than 8-ft/s (2.4-m/s), the surge potential can be as high as 400-psi (2760-kPa). Also, when the fill velocity exceeds 2-ft/s (0.6-m/s), high surges can result.
What are types of valves?
Common types of valves include:
- Ball Valve. Predominantly equipped with quick-acting 90-degree turn handles, these valves use a ball to control flow to provide easy on-off control.
- Butterfly Valve.
- Check Valve.
- Gate Valve.
- Knife Gate Valve.
- Globe Valve.
- Needle Valve.
- Pinch Valve.
What is difference between swing type and wafer type check valve?
The difference between the two is in the body design. Swing check valves are not designed for extremely tight spaces like the wafer check. They have molded bodies around the area where the disc opens up. This is the most important difference between the two types of valve.
How far should a check valve be from a sump pump?
Best height ( unless owner’s manual states otherwise) is two to three feet off of the top of the sump pit. This way your sump pump motor doesn’t have to work as hard as when your check valve is in lower position. It will open easier due to the reduced weight of water above it.
What is a wash out valve?
Washout valves are used for normal maintenance work of watermain like allowing flowing out of water during cleaning of watermain. At the junction where a tee-branch out to a washout point, a gate valve is installed to separate the two pipelines.
What are the advantages and disadvantages of gate valves?
What are the advantages and disadvantages of gate valves?
- Gate Valves Have Low Fluid Resistance.
- Gate Valves Provide Superior Sealing Performance.
- Gate Valves Have a Wide Application Range.
- Gate Valves are Bidirectional.
