Globe Valves

Product catalog summary
Overview
SchuF Globe Valves are engineered for medium-to-severe service applications across industries such as refining, petrochemical, power, and chemical. They are available in a variety of materials, from carbon steel to exotic alloys, and in ASME Class 150# to 2500#. These valves ensure tight shut-off and can be customized for higher pressures or specific material needs.
Types of SchuF Globe Valves
  • Y-Pattern Globe Valves: Designed to minimize pressure drop while maintaining sealing performance, available in bolted bonnet and pressure-seal designs.
  • Stop-Check Valves: Function as Y-Globe valves with additional check-valve protection against backflow.
  • Blow-Down Valves: Used to remove impurities from boilers, available in intermittent and continuous designs.
  • Special Designs: Include high-pressure angle valves for low-pressure drops and straightway and P-Globe valves for high Cv and low pressure drop.
Standards and Applications
SchuF valves comply with standards such as ASME B16.34, API 598, and EN 12266. They are used for maintenance isolation, emergency shut-off, and processes like hydroprocessing and power generation. Materials include Incoloy, Super-Duplex, Hastelloy, and Titanium.
Y-Pattern Globe Valves
  • Bolted Bonnet, ASME 150-600: Features include a rugged single-piece spindle and disc, flexible material combinations, and replaceable seats for tight shut-off and low pressure-drop.
  • Bolted Bonnet, ASME 900-2500: Offers low fugitive emissions, a double packing arrangement, and a sniffer port option for higher pressure applications.
  • Pressure Seal, ASME 900-2500: Lighter in weight for higher pressure classes, with a pressure seal ring and retaining ring.
  • Straightway, ASME 150-2500: Features a unique Ram-Seal mechanism for positive shut-off, high Cv values, and low pressure drops.
  • Piggable ‘P-Type’, ASME 150-1500: Offers full-bore unimpeded flow, highest Cv, and lowest Delta P with an M-Seal design for drop-tight shut-off.
Stop-Check Valves
  • Types: Y-Type (ASME 150-1500 Type 55SC) and Angle-Type (ASME 150-1500 Type 55SA).
  • Functionality: Combines isolation and check-valve functions, preventing back-flow with a spring-assisted disc.
  • Features: Double packing arrangement for low emissions, hard-faced sealing surfaces, and various actuator options.
  • Specifications: Sizes range from DN 25 (1”) to DN 600 (24”), with pressure classes from ASME 150 to ASME 600.
Blow-Down Valves
  • Types: Continuous and Discontinuous/Intermittent, available in Angle-Type and Y-Type designs.
  • Purpose: Remove dirt, scale, and sediment from boilers to maintain efficiency and integrity.
  • Features: Double packing arrangement, non-rotating stem, live-loaded packing option, and replaceable seat construction.
  • Specifications: Sizes range from DN 25 (1”) to DN 600 (24”), with pressure classes from ASME 150 to ASME 600.
Standards and Certifications
All valves comply with ASME B16.34, API 598 & 623, NACE MR0175, EN 12266, and Dir. PED 97/23/EC standards.
Actuation Options
Valves can be manually operated or equipped with electric, pneumatic, or bevel-gear actuators.
Key Advantages
  • Low fugitive emissions due to double packing arrangements.
  • Quick and easy maintenance.
  • High-pressure letdown capabilities with multi-stage trim options to prevent cavitation and noise.
Tandem Blow-Down Valve
This valve combines the functions of blowing and sealing, reducing issues related to separate valve connections and saving space.
Three-Way Globe Valve
Serves as both a flow blending and flow-diverting valve, suitable for isolating and controlling gases and steam at moderate pressures and temperatures.
High Temperature and Bellows-Seal Applications
SchuF manufactures Y-globe valves for high-temperature environments, using materials like Incoloy 800HT, designed to minimize heat transfer to actuators and are fire-safe certified.
Customer Enquiry Sheet
Includes a template for customer inquiries, capturing company information, order details, and specific valve and process information.

Globe Valves Overview SchuF Globe Valves are isolation valves designed to withstand medium-to-severe service applications, ranging from low-pressure steam to high-pressure hydrogen. The construction materials of the valves range from standard carbon steel to EXOTIC ALLOYS and from Class ASME 150# to Class 2500# ratings. Refining, petrochemical, power and chemical industries rely on SchuF Globe Valves for absolute tight shut-off. Should higher pressures or material grades be required, SchuF engineering has the know-how to custom-build valves to meet those demands. Applications include:    ...
