Pipe Valves is rooted in industrial pipe, valves, and fittings but also has engineered process solutions for steam, hot water, humidification, valve actuation, controls, instrumentation, sanitary processes, corrosive fluid handling, and commercial plumbing and drainage.
Common Valve Connections And Ends
Screwed or Threaded: Often used in instrument connections or sample points
Flanged: The most common ends for piping use
Butt Welded: Typically used in high-pressure or high-temperature operations
Socket Welded: Commonly used on small bore piping where threaded connections are not permitted
Wafer and Lug: Often used for compact valves installed in systems with limited space
Valve Materials
- Stainless Steel
- Carbon Steel
- Alloy Steel
- etc.
DIAMETER RANGE
Our valves are available for 2 to 60 inch pipe diameters. Consult the team at Union Steel for larger sizes.
PRESSURE CLASS
Union Steel manufactures valves according to CWP, ANSI 150, ANSI 300 and ANSI 600 standards. From low pressure gravity fed applications to systems with 1500 PSI.
VALVE BODY & TRIM MATERIALS
Union Steel valves have no limitations on the type of materials such as Stainless Steel, Titanium or Platinum.
As metallurgy is highly dependent on application specifications, our control valves are available in dozens of standard and exotic materials (e.g. Carbon steel, 316 Stainless steel, Hastelloy, SuperDuplex, Titanium, etc).
Depending on your intended usage, you might find that valves must adhere to particular standards to meet regulatory requirements for safety, sanitation, or other concerns. While there are too many standard organizations and potential regulations to cover in detail, common general standard organizations include:
CSA Group (CSA)
The American Society of Mechanical Engineers (ASME)
The American National Standards Institute (ANSI)
The American Society for Testing Materials International (ASTM International)
The Manufacturers Standardization Society (MSS)
The International Organization for Standardization (ISO)
The Public Health and Safety Organization (NSF)
NACE International (NACE)
The American Petroleum Institute (API)
American Water Works Association (AWWA)
There are also industry-specific standards to consider.
Major standards organizations by industry include:
ASHRAE Valve Standards
ASME BPVC Valve Standards
ASSE Valve Standards
ISA Valve Standards
NFPA Valve Standards
SAE Valve Standards
