Many water heaters come with a drain valve that has a cone shaped handle. They spell trouble. Other makers of water heaters have a plastic faucet type drain valve. This type of drain valve is prone to breaks and leaks. The better types are the brass hose bibb, not unlike the average garden hose bibb. Even better would be brass ball valve. This type of drain valve would have a lever that can either be open or shut. The brass ball valve allows the most effective flushing of the water heater.
The ball valve controls the flow and temperature of the water by using a steel ball. The...
Ancient Chinese artifacts, the most widely used and significant brass ball valve differences, different shapes of the incense burner in the case.

As you can tell if you have been reading these recent posts I'm working on gas valve design. We are going to need good control of very low flow rates. Very low. On the order of 1E-3 to 1E-6 cc/second at STP.
A gas valve with a major orifice .200" in diameter will not give us much control. It goes from fully on to fully off (at the very low flow rates required) with a travel of .1 thousandth of an inch. What can be done to increase the travel and also increase the flow control?
Angle the sealing plate (assuming a soft seal such as an O-ring). This will give more control as the v...
Ball valves has a muted yellow color, somewhat similar to gold. It is relatively resistant to tarnishing, and is often used as decoration and for coins. In antiquity, polished brass was often used as a mirror.
Brass is the proportions of zinc and copper can be varied to create a range of brass ball valvewith varying properties.In comparison, bronze is principally an alloy of copper and tin.
Despite this distinction, some types of brasses are called bronzes. Brass is a substitutional alloy.www.brassvalvechina.com It is used for decoration for its bright gold-like appear...
Knife gate valves are produced in stainless steel to prevent corrosion problem that is prevalent with cast iron or steel valves lined with stainless steel. They are designed for wide range of industrial use like pulp & paper, water treatment, power generation, chemical industries, food & beverage processing, etc. SVC is one of the specific designed valve among other Industrial Valves. This design ensures minimum contact between the parts of the valve thus reducing wear & tear. The high performance Knife Gate Valves features, available in sizes from 2†to 24†di...
June 26, 2009 - With ability to stop flow without leakage, construction size 22 valves are suited for structural engineering works, such as lifting, moving, and depositing decking elements on bridges and production test benches. They can be arranged for direct control of hydraulic consumers or as pilot valves for hydraulic activated switchgear. Available in solenoid, pilot, mechanical, or manual actuations, valves can be delivered with 2/2-, 3/2-, and 4 position 3-way directional functions.
Analyze the application to determine which valve is best suited for installations, keeping in mind the service for which the valve is recommended. Before installing the correct valve, review the installation instructions to prevent damage to the valve and to assure its maximum efficiency.
1.Cut tube end square. Ream, burr and size.
2.Use sand cloth or steel wire brush to clean both ends to a bright metal finish. Steel wool is notrecommended.
3.Apply flux to outside of tube and inside of solder cup. Surfaces to be joined must be completely covered. Use flux sparingly.
4.Be sure that ...
The booster has a precisely manufactured bypass restriction, which means it can be adjusted exactly and lead-sealed in this setup, saving time and reducing potential start-up problems.
As the booster is completely pressure balanced it provides a stable output, even under fluctuating pressure conditions.
The signal pressure is transmitted with a defined hysteresis, without loss (gain 1:1) and emits minimal noise.
Another important benefit is that only the booster's functional parts come into contact with instrument air.
Alternatively, the booster's exhaust air port can be protected fr...
The Dual Plate Check Valve is an all purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing check valve or lift check valve.
