Everything you should know about check valve

Valve Check – How Do They Work? A check valve is a device that only allows the flow of fluids in one direction. They have two ports, one as an inlet for the media and one as the output for the media. Since they only allow media flow in one direction, they are commonly referred to as ‘one way valves’ or ‘non return valves.’ The main purpose of a check valve is to prevent backflow in the system. Figure 1 shows an example of a check valve. A check valve relies on a pressure differential to work. They require a higher pressure on the input side of the valve than the output side to open the valve. When the pressure is higher on the outlet side (or the input side pressure is not high enough), the valve will close. Depending

1/4’’ SAE Service Access Valve with Core & Cap Stem Remover

Filling Access Valve for Air Conditioner Refrigerant System   Features Each valve has a core and a cap with valve core remover, it can be bent, cut, flared, or swaged to meet application requirements. The core is a poppet valve assisted by a spring that is threaded into the steam. Constructed with high-quality brass, the cap is wear-resistant and durable. And it’s provided with core remover and have an inside rubber o-ring. 1/4” SAE x 1/4” O.D. x 4″ stem. The stem is a self-contained valve which opens to admit gas to a chamber.

What is Custom Valve Manufacturing? and versus Mass Produced Parts.

What is Custom Valve Manufacturing? In the valve manufacturing world, there are two primary types of products – mass-produced stock items, also known as off-the-shelf products, and custom-manufactured items, where a customer can have a greater say in what they want. Valve Mass production came about as a consequence of the industrial revolution. What mass production offered to consumers was greater access to products of uniform quality at reduced prices. The tradeoff was that customers had less control over the exact details of the product that they received. As Fanovo’s president once said in regard to custom valve manufacturing, “our mission is to make the purchase of valve plumbing painless for global clients.” This quote underscores one of the key differences between mass-produced versus custom products – consumer choice. ­One of the ways in which mass production reduces costs is to

Everything You Should Know About Peep Sight Custom Manufactured by Fanovo

What is Peep Sight (namely sight glass) ? When visibility is required in a small pipe or a small chamber, peep sights provide visibility that won’t compromise the durability of your equipment. Gage sight Glass supplies peep sights that are built to withstand high pressure and temperature conditions without warping or cracking. With many different types of peep sights available in different sizes ranging from ½ inch to 2.5 inches and built to withstand different vessel conditions, you can find the right peep sight for your applications.   What is the main function of sight gauge? Peep sights allow technicians, inspectors, operators and other users to look into potentially media flow environments without the need to enter or open the space. When working with high-temperature environments, hazardous or caustic fluids or gases, high-pressure tanks or other chambers that should not
