What is difference between WCC and WCB?
CARBON STEEL VALVES WCB/WCC/A105 Carbon steel valves are kept in stock in forged ASTM A105 and it’s cast equivalent ASTM/A216-WCB. ASTM A216 WCC has a slightly higher pressure/ temperature rating than A216 WCB as it has a higher yield strength and a slightly higher manganese content.
What is WCA WCB WCC?
ASTM A216 WCA, WCB, WCC (CARBON STEEL HIGH-TEMP.) The ASTM A216 specification covers 3 grades of carbon steel (WCA, WCB, and WCC), which feature slight differences in terms of chemical and mechanical properties. These grades for cast valves bodies match carbon steel pipes in grades A53, A106, API 5L.
What does WCB mean on a valve body?
A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. This has an opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve.
Is globe a valve?
Valve trim is the physical shape of the plug and seat arrangement. The shape of the valve plug determines the flow characteristics of the valve. Different valve characterizations may be achieved by re-shaping the valve trim.
What is Valve trim?
It is a complex mechanical device manufactured by assembling a number of different components: the body (the pressure containing shell, made of cast or forged steel, available with flanged, threaded or socket weld connection to pipes), the bonnet, the trim (the disc, the seat, the stem, and the other wet parts), the ...

Common types of valves include:
What are types of valves?
Valve Flow Coefficient (Cv) is the flow capability of a control valve at fully open conditions relative to the pressure drop across the valve. It is defined as the volume of water (GPM in the US) at 60°F that will flow through a fully open valve with a pressure differential of 1 psi across the valve.
What is CV in a control valve?
Cv by definition is the number of gallons per minute (GPM) a valve will flow with a 1 psi pressure drop across the valve. For example a valve with a Cv of 10 will flow 10 GPM with a 1 psi pressure drop. The formula used to select the valve Cv with the specified differential pressure is: Cv=GPM/((SQ RT(∆P)).
How do you calculate valve CV?
Converting between Flow Coefficient Cv and Flow Factor K. The relationship between Cv and Kv can be expressed as: Cv = 1.16 Kv (1) Kv = 0.862 Cv (2)
How do you convert KV to CV?
In the U.S. system of units, the Cv coefficient is the number of U.S. gallons per minute of water that will pass through a given orifice area at a pressure drop of 1 PSI. The definition of Cv is based on water, which has a G (specific gravity) = 1.0.
What is CV unit?
Kv and KVS provide information about the flow that will pass through a valve: KV is the flow that generates a pressure drop of 1 bar at a given degree of openness . KVS is the flow that generates a pressure drop of 1 bar when the valve opening is maximum.
What is the difference between KV and KVS?
KVS
What does KVS stand for?
Acronyms to know: KVS. kitchen video system (monitors in grill)
What does KVS mean in Mcdonalds?
Later, the name was changed to Kendriya Vidyalaya. It is a non-profit organisation. Its schools are all affiliated to the Central Board of Secondary Education (CBSE). Its objective is to educate children of the Indian Defence Services personnel who are often posted to remote locations.
Is kV a Army school?
Yes, you can learn much more than any private schools in KV. It gives more opportunities not only in academics but also in sports or curricular activites that leads to better personality development of students.
Is KV better than private school?
The Kendriya Vidyalayas were established in 1963 with the sole purpose of offering quality education to the children of transferable central government employees, including those in the defence and paramilitary services. The KVs are cheaper than most popular private schools and some sub-par ones as well.
