ANSI Carbon Steel Gate Valve

The 1704 ANSI Carbon Steel Gate Valve is an industrial isolation valve for ANSI-pattern process piping. Its carbon-steel, bolted-bonnet form supports conventional gate-valve service, while final size, pressure class, trim, end connection, and media compatibility should be confirmed from the approved product documentation.

Designed to International Standards

GB API ASME ANSI JIS BS DIN

The 1704 ANSI Carbon Steel Gate Valve is an ANSI-pattern, carbon-steel gate valve for process-piping isolation. Its bolted-bonnet configuration and outside-screw, rising-stem form distinguish it from compact non-rising-stem water-service gate valves. Use it for on/off duty after verifying the selected construction against the application requirements.

Key Features

  • Carbon-steel gate-valve construction.
  • Bolted-bonnet configuration.
  • Outside-screw, rising-stem operating form.
  • ANSI-pattern layout for industrial process piping.

Applications

Selection considerations: confirm fluid compatibility, pressure class, temperature conditions, end connection, trim, and required design documentation before ordering.

One Plant, Start to Finish

Designed, Machined and Tested Under One Roof

CAD design, machining and pressure testing all happen inside the plant before a valve ships.

100,000 Valves Produced a Year Produced in an 8,000 m² manufacturing plant.
Quality Control Before Dispatch
  • SPECIFICATIONCheck the drawing and order confirmation against each valve before dispatch.
  • MATERIALIdentify and trace material certificates for each production batch.
  • DIMENSIONSRecord dimensional inspection results for the valves in an order.
  • PRESSURE TESTRecord a shell and seat pressure test for every valve.
  • DOCUMENTATIONControl document revisions so drawings match production.
  • CERTIFICATIONPrepare certification documents. Accept third-party inspection appointed by the buyer.

Six Valve Categories From One Plant

Butterfly, ball, gate, globe, check and hydraulic control: six valve categories from one plant.

Valve Manufacturing Process
  1. 01Design each valve in CAD before it reaches the shop floor.
  2. 02Identify and mechanically test material before machining starts.
  3. 03Machine valve components on CNC lathes and boring machines.
  4. 04Spray-weld the seating surface with plasma equipment.
  5. 05Inspect welds and castings with non-destructive and ultrasonic testing.
  6. 06Pressure-test the shell and seat of every valve before dispatch.
