Stop Check Globe Valve Bolted Bonnet Fluitek

Stop-check globe valve with bolted bonnet, designed for lines requiring both isolation and reverse flow protection. The stop-check function allows full closure when the stem presses the disc into the seat, while with the stem in the upper position, the disc operates as a lift non-return check valve.

Construction

  • Body configuration: straight pattern / T-pattern globe
  • Construction: cast body and cast bonnet
  • Bonnet: bolted
  • Connections: flanged or butt weld
  • Pressure rating: ANSI Class 150, 300, 600
  • Materials: carbon steel, low alloy steel, austenitic stainless steel, duplex stainless steel, nickel alloys
  • Material standards: ASTM/ASME or EN, depending on design conditions

Functional Application

The valve is used in steam, water, condensate, feedwater, auxiliary circuits, and process fluids. It is beneficial in lines where the same valve must provide:

  • positive line isolation
  • reverse flow restriction
  • protection of pumps or downstream equipment
  • manual closure for maintenance or unit startup

Selection Criteria

Selection should be based on pressure class, temperature, differential pressure, end type, flow direction, and material compatibility with the medium. In applications with frequent cycles, seat/disc wear and packing tightness should be checked.

Indicative Sizes Class 600

The technical sheet provides an example of ANSI 600 from 2" to 12", with bore 51–298 mm, face-to-face 292–838 mm, and weights 34–1098 kg. Sizes above 12" are specified per application.

Certifications

Available compliances: ISO 9001:2015, PED 2014/68/EU, ATEX 2014/34/EU, IEC 61508 SIL, API 6A / ISO 10423, API 6D, API 6DSS, and TR-CU.

FAQ

How does it differ from a simple globe valve?

Yes. A simple globe valve primarily provides isolation or throttling. The stop-check globe adds lift check functionality when the stem does not hold the disc closed.

Can it replace a separate check valve?

It can reduce the number of components in specific lines, but hydraulic conditions, flow direction, and required backflow tightness must be verified.

Datasheet and documents

Description

FLUITEK ORSENIGO VALVES has introduced a complete line of this type of product. Their function is to combine the off service by blocking the disc in the closed position, with a lift non return check valve service, when stem, not firmly connected with the disc, is in the up position. Construction is with straight pattern (also called “T-pattern”). Normal construction is with cast body and bonnet. Ends configuration is either with flanged ends or with butt weld ends. Materials range from carbon steel to low alloy steel, to austenitic stainless steel, to austenitic-ferritic stainless steels (duplex), to nickel alloys.

Materials are either to ASTM/ASME standards or to EN standards, either harmonized or calculated to design conditions. Pressure classes (per ANSI standard) are normally ranging from 150# to 300# to 600#.
