Product Description

 

Product Description

Complex type fast exhaust valve
Production introduction
This product is used at the highest point of pipelines, the place where air is shutoff, or the outlets of pumps in order to eliminate air and dredge pipelines, If the vent valve is not set, the air in the pipeline willbe possibly shutoff at any time, and the water content will not meet the design requirement. If the electricity is suddenly cut off when the pipeline is at work, the negative pressure in the pipeline willcause vibration or cracking. In this case, the vent valve can quickly inhale air into the pipeline and prevent the vibration and cracking of it.

Operating Principle

There are two holes in the compound vent valve, one big, one small. The diameter nearly equals DN. The frist time water is passed in the pipeline, a large amount of air will be released through the big hole stops working. When the pipeline is at work, air cells will be generated. And air cells will grow bigger while move moment, these air cells can be removed through the small hole. There fore no air exist in the pipeline. When the electricity is cut off, the pump does not work, or there is no water floe in the pipeline, negative pressure will be generated and there will be a great need of air in the pipeline .In order to inhale a lot of air,a floating ball willfall and open the small hole which will drive the opening of the big hole.
Warning: The working pressure of vent valve cannot be over 0.02Mpa,if not,water will be leaked. And this valve should be equipped with another valve for maintenance.

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 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

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:

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
