Description

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 Types of Valves

Ball Valve                               Butterfly Valve                           Check Valve                            Gate Valve                         Knife Gate Valve

Globe Valve                          Needle Valve                              Pinch Valve                                   Plug Valve                      Pressure Relief Valve

Y Strainer Valve

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.

Specification

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).

Standard

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
