What the 300lb American Standard Globe Valve A216GR stands for

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

This is the American Society for Testing and Materials (ASTM) standard number.

ASTM A216 Standard Specification for Meltable Carbon Steel Castings for High Temperature Applications is available in three grades: WCA, WCB, WCC.

GR is an abbreviation for GRADE.

This material is the WCB in the national standard

A216 GR WCB is the abbreviation of ASTM A216 Grade WCB.

It is a heat-resistant weldable carbon cast steel, and its chemical composition is close to that of domestic cast steel ZG 275-485 h. A216 is the U.S. designation.

A216 GR WCB is the abbreviation of ASTM A216 Grade WCB, which means American Standard Row Number WCB, which is a material made of carbon steel casting. Therefore, WCB means cast steel, and cast steel is generally WCB, CF8M, CF3, etc.

ASTM A216 GR-WCC: American Standard Carbon Steel.

SCS1: Korean material, corrosion-resistant steel, and SCS2.

German standard, **(x2crnimo17-12-3), stainless acid resistant steel material.

SUH3: Japanese standard material (the specific content of manganese, I won't mark it, it's too complicated) hardfaced stellite6: This is the answer of the brother upstairs.

Hope it helps!

Please refer to the comparison table for the corresponding national standard

Ball valve, body is WCB A216, ball body is 304, valve seat PTFE, raised flange connection, full bore, pressure is 150lbThis is a very common American standard flanged ball valve.

PTFE is PTFE, which is the material of the mat inside. The others are the same as the upstairs.

The most common low-pressure cast steel gate valve, pressure class CL150, body material cast steel, spool material: 13cr heat treatment, bolted bonnet, open rod bracket shape, flange connection, flange face connection form RF, in accordance with API600 American gate valve standard.

Hello. Lucky to see your question.

It may be that the question you are asking is a bit more professional than anyone will. Or someone else hasn't encountered or touched your problem, so they can't help you. It is recommended that you go to the relevant forum for help, where there are usually more people and more enthusiastic, and may be able to help you solve the problem quickly.

Good luck!

Are the internal parts you referring to seals, if they are seals, they are generally NBR EPDM PTFE these materials.

Valve trim usually refers to the valve stem, seat sealing surface, disc sealing surface, common internals, 1 is 13cr, that is to say, the stem material is 13cr, the seat is 13cr, the disc material is 13cr or the sealing surface on the disc is 13crFor example, if the gate valve 1 trim made of WCB material is clear, that is, the stem material is 13Cr, the seat A105+13Cr, and the disc is WCB+13Cr

By analogy, 5 trim full STL, that is, the disc and seat fully welded STL, 8 is half STL, seat A105+STLNote that the 5 stem is 13CR, not the STL stem, and the 10 trim is 316 and the stem is also 316.
