Swagelok Valve for Chlorine Service: Ball Vent and Carbon Steel Body

Swagelok's C60V Series valves, designed for chlorine applications, combine carbon steel bodies with virgin PTFE seats for optimal safety and adherence to Chlorine Institute guidelines. These valves feature a ball vent to prevent overpressurization, undergo rigorous testing for reliability, and are meticulously cleaned and packaged for immediate chlorine service use.

Swagelok's Chlorine Series (C60V Series) valves are designed with specific materials to ensure safety and reliability when handling chlorine applications. The valve body is made of carbon steel, paired with virgin PTFE seats and packing.

This construction adheres to the stringent guidelines in Chlorine Institute Pamphlet 6, which covers Piping Systems for Dry Chlorine, ensuring compatibility and safety in chlorine service environments.

These valves also feature an upstream ball vent that prevents overpressurization in the ball and body when the valve is closed, further enhancing operational safety and reliability. C60V valves offer pressure-temperature ratings of 300 psig at temperatures ranging from –20 to 250°F (20.6 bar at –28 to 121°C), good for a range of chlorine service applications.

Readiness for immediate use

For cleanliness and safety, the valve bodies and flanges undergo a two-step cleaning process:

• First, with mineral spirits
• Second, with aqueous cleaning solution containing a surfactant

(All other wetted components are cleaned according to Swagelok's Special Cleaning and Packaging SC-11 standards.)

Capped, sealed, and tagged

To ensure their integrity and readiness for chlorine service, C60V series ball valves are individually capped and sealed in desiccant packaging. And each valve is tagged for chlorine service, emphasizing its specialized use.

Moreover, every valve within the chlorine series undergoes rigorous factory testing, including both seat and shell tests with nitrogen at 300 psig (20.6 bar). These tests are stringent, with seats having a maximum allowable leak rate of 0.04 std cm^{^}3/min, ensuring the valves meet high standards of quality and reliability for handling chlorine.

Special alloys

Swagelok carries an array of special alloys to meet our customer's requirements. Two important pieces to note:

• Alloy 600, a nickel-chromium-iron alloy. This strong alloy is highly resistant to chloride-ion induced stress corrosion cracking.
• Titanium alloys. They have excellent resistance to corrosion in a wide variety of environments including seawater, salt brines, inorganic salts, bleaches, wet chlorine, alkaline solutions, oxidizing acids and organic acids.

There is often an elevated chlorine level in boiler water, for example. Chlorine and stainless steels don’t mix well and it is common to find stress corrosion cracking in applications that have high chloride levels and stainless steel fittings and tubing. Again, there are a number of materials that we offer that can provide the necessary corrosion resistance in this type of application.
