Serie 6400-6600

Product catalog summary

Overview: The document details the specifications and features of the Series 6400 and 6600 safety valves, designed for intermediate power boiler and organic fluid vaporizer service. These valves comply with the ASME Boiler and Pressure Vessel Code, ensuring certified capacities at 3% overpressure.

Key Features:

Compliance with ASME Code Sections I and VIII for steam service.
Full nozzle design for reduced maintenance and a hardened conical disc for extended seat life.
Monel or copper nickel alloy guides for high-temperature models to reduce galling.
Set pressure capability up to 1500 psig and temperatures up to 1000°F.
Available in closed bonnet or exposed spring versions with dual blow down rings for precise performance.

Materials: The valves are constructed from materials such as carbon steel, stainless steel, Monel, and alloy steel, chosen based on temperature and pressure requirements.

Valve Specifications: Detailed tables provide specifications for different valve sizes, types, and pressure settings, including maximum set pressures and back pressures for various configurations.

Steam Capacities: Tables show steam capacities at 3% overpressure, with capacities listed in pounds per hour at saturation temperature for various pressure increments.

Superheat Correction Factor: A table provides correction factors for superheated steam at different temperatures, ensuring accurate capacity calculations under varying conditions.

General Notes: Additional notes clarify options for valve configurations, such as optional test gags, cap constructions, and specific requirements for organic fluid vaporizer service.

Specifications: The document outlines sizing equations for steam service and organic fluid vaporizers, detailing parameters like required orifice area, relieving pressure, inlet temperature, required steam capacity, and required vapor capacity. The coefficient of discharge and steam superheat correction factor are also specified.

Valve Dimensions and Weight: Various valve models are listed with their dimensions and weights, categorized by inlet and outlet sizes, pressure ratings, and other physical dimensions.

Standards and Compliance: The valves conform to the ASME Boiler and Pressure Vessel Code, ensuring they meet industry standards for safety and performance.

Recommendations: The document advises on the correct use of the valves, emphasizing adherence to specified sizing and pressure guidelines for optimal performance and safety.

Additional Information: Contact information for Farris Engineering is provided, along with notes on the company's global facilities and offices. A disclaimer regarding the accuracy and reliability of the information is also included.
