Triple Eccentric Valve / ISO 5752

ISO 5752 Triple Eccentric Butterfly Valve For Water Service

TJL's ISO 5752 Series 13 triple eccentric butterfly valve gives project teams a starting point for standards, flange connection, body material, sealing structure, and media fit. Review the specification with an industrial butterfly valve manufacturer or a butterfly valve supplier when fresh water, sewage, sea water, or air service is part of the inquiry.

Service-Media Checks

Separate Media Conditions Before Confirming The Valve

The same product table can support different service discussions, but the final inquiry should still name the actual medium, pressure, temperature, and material expectations.

Fresh Water

Confirm Pressure Class

Match the nominal pressure and seal/shell test values before selecting the valve for clean-water service.

Sewage

Review Sealing Structure

Discuss how the NBR sealing ring, stainless steel seat, and replaceable sealing design fit the application's solids and maintenance expectations.

Sea Water

Check Material Exposure

Use the material list as a starting point, then confirm corrosion and anti-scouring expectations for the project environment.

Air And Other Media

Name Operating Conditions

Include temperature, pressure, flange standard, actuator preference, and installation notes when the service is not a simple water line.

Standards And Performance Table

Keep Standards, Dimensions, And Test Values Together

For a triple eccentric butterfly valve inquiry, standards references and performance values should travel together so the supplier can check the requested configuration efficiently.

Design standard	BS EN593, BS5155, API609, DIN3354
Face-to-face dimension	ISO 5752 Series 13 and 14, BS EN558 Series 13 and 14, API609, DIN3202, ASME B16.10
Flange connection	AWWA C207, DIN 2501 PN10-16-25, EN1092 PN10-16-25
Driving-device flange	Connecting bracket complying with ISO5211
Nominal diameter	DN100-DN2600, DN100-DN1200, and DN600-DN300 ranges appear by pressure grouping
Nominal pressure	1.0, 1.6, and 0.6 are listed in the performance table
Test pressure	Seal: 1.1 / 1.76 / 0.66; shell: 1.5 / 2.4 / 0.9
Applicable temperature	-10C to 100C

Material And Sealing Stack

Align Body, Seal, Seat, Stem, And Sleeve

Material names are most useful when they are tied to the component they describe. Use this stack to prepare a clearer specification discussion.

Body And Seat

Ductile iron body
Inlaid or surfacing welded stainless steel valve seat
Seat described for anti-scouring ability

Sealing Structure

V-type NBR nitrile rubber sealing rings
4-6 pieces named in product details
Adjustable sealing at the upper shaft end

Stem And Torque Transfer

Eccentric double half-shaft stem design
Copper alloy shaft sleeve
Cylindrical pin for torque transfer
