Gauge Valves and Instrumentation Manifolds

Product catalog summary

Overview: This document outlines the specifications and guidelines for gauge valves and instrumentation manifolds, focusing on the GV, GVH, and GR series, as well as 2-valve, 3-valve, and 5-valve manifolds. It includes details on types, dimensions, materials, features, and pressure-temperature ratings.

Types and Dimensions: Manifolds are categorized into remote mount and direct mount types, with distinctions based on flange types such as coplanar, traditional, kidney, and eccentric. The document also covers bleed valves, calibration fittings, and manifold bracket supports.

Materials and Construction: Standard materials include 316 SS/A479, 304 SS/A479, and zinc-plated carbon steel, with compliance to NACE MR0175/ISO 15156 for sour gas service emphasized.

Features: Key features include non-rotating lower stem designs, safety back seating seals, rolled spindle threads, and externally adjustable glands. Valves are designed for low torque operation and offer options for different colored handles.

Pressure vs. Temperature: The GV and GR series can handle pressures up to 6000 psig, while the GVH series can handle up to 10000 psig. Temperature ranges vary based on packing and seat materials, with PTFE and graphite options available.

Testing and Standards: Each valve is leak tested with nitrogen or compressed air, and GVH series valves are tested with water at 1.1 times the maximum working pressure. Pressure-temperature graphs for different series are included.

Ordering Information: Detailed ordering information, including part numbers and descriptions, is provided to assist in selecting the appropriate valve configuration.

Additional Series Overview: The document also covers the EF Series (Eccentric) and KF Series, providing technical specifications and ordering information. It includes details on mounting manifolds, connection types, and dimensions.

Specifications: Basic ordering numbers for different series, including the EF and KF Series, are listed along with their connection types and sizes. Dimensions are provided in inches and millimeters.

Block and Bleed Valves: Several series of block and bleed valves, including BB, DB, SB, and DBB Series, are mentioned as essential for isolating and bleeding off pressure in instrumentation systems.

Calibration Fittings: Calibration fittings are highlighted for providing rapid access to cells for calibration purposes, noting that accessing the port of a DP transmitter requires the removal of the vent port tap.

Bleed Valves: The RB Series Bleed Valve is identified as a standard test/vent valve, with additional information available in the FITOK Bleed Valve RB Series catalog.
