Change the valve.
Not the pipework.

MODU ONE® is a Modular Valve Ecosystem. Every body shares one connection interface and one face to face dimension, so the piping never changes.

One valve, one dimension.

An A10 three piece ball valve, DN25, with ISO 1127 welded ends. The number on the left is the face to face dimension, and it is the only thing on this page that will not change.

Undo four tie bolts.

Four tie bolts hold the centre part between two end caps. The end caps are welded into the line once. Everything after that happens between them.

A10 in the pipe, nuts off and tie bolts drawn out, end caps still in the line.
Tie bolts out.

The centre part lifts out.

The ball valve centre part comes straight up and out. The end caps do not move. The pipework does not move. Nothing is cut and nothing is welded.

The centre part removed, the two end caps still welded in the pipe with an empty gap between them.
An empty gap, the line untouched.

A different body seats in.

A B10 soft seated check valve centre part seats into the same end caps. A ball valve became a check valve without touching the line.

Seated into the same end caps.

The number did not move.

Different valve, different function, same 140 mm. That holds for every connection standard MODU ONE® offers, threaded and welded, in full bore and reduced bore, and it holds at every size.

The ecosystem

Four things that do not change.

One face to face dimension

Shared across every body and every connection standard. 105 to 260 mm, by size, held to ±1 mm.

One connection interface

The same bolted end caps take threaded BSPP and NPT, ISO 1127 and SMS 3008 welded ends, in full bore and reduced bore.

Shared service parts

The seat ring in a B10 check valve is the same part as the seat ring in an A10 ball valve. Gasket kits are shared across the ecosystem.

Full traceability

Every valve has its own serial number on the body and the connections. All wetted parts are traceable in MODU Cloud™.

Face to face

Six valve types. One face to face.

Pick a valve type. The dimension at every size stays where it is.

Supported connections

Seven connections. The face to face does not change.

The connection sits on the end cap. Weld it, thread it or clamp it: the valve keeps the same face to face at every size, for every connection type.

Features

Built into the ecosystem.

Double Block & Bleed™

Two A10 ball valves and one drain valve on one MODU block. Two separate barriers, and the LUG design lets you service each valve on its own.

Datasheet PDF

Integrated Heating

A heating jacket replaces the standard flange. Steam or hot water keeps viscous media fluid in the valve body. Four ports, and service without a stop in the heating circuit.

Datasheet PDF

MODU Safe Mounting®

A guided interface between ball and actuator. The actuator goes on one way only, so SCADA and PLC always show the true valve position.

MODU Multi-Purpose Port™

One port in every MODU ONE® connection for a thermometer, pressure gauge, air vent or drain valve. No welding. Drain and vent without removing parts.

MODU ONE® Traceability

Every valve is checked and has its own serial number. The certificate covers the materials, and also the valve torque and the torque of nuts and bolts.

What is a modular valve?
A modular valve shares the same face to face dimensions, spare parts and connections with the other valve types in its ecosystem. You can change one valve type for another without changing the pipework, and it stays backwards compatible.
What size range does MODU ONE® cover?
DN8 to DN100 (¼″ to 4″), depending on the valve type. The A10 ball valve and the B10 check valve are dimensioned from DN15 to DN100 in both datasheets; the A10 also comes in DN8 and DN10.
Does MODU ONE® come in both full and reduced port options?
Yes. MODU ONE® is offered in both full bore and reduced bore.
What is the pressure class of MODU ONE®?
The A10 ball valve is PN40. The B10 check valve is PN63. See the datasheet of each valve for the pressure and temperature limits.
Which material is used to manufacture MODU ONE®?
A10, B10, C10, D10, E10 and F10 are made of stainless steel CF8M (1.4408).
Do the connections change the face to face?
No. Each size has one face to face for every connection type: welded, threaded or hygienic.
Where are you headquartered?
In Vejle, Denmark, together with MODU Valves A/S at Løversysselvej 4, 7100 Vejle.
Where can I access MODU Cloud™?
At cloud.modu-one.com. Search by serial number and download your certificates.
Who is behind MODU ONE®?
A team of valve specialists in Vejle, Denmark, with decades of experience. MODU ONE® is owned by MODU Valves A/S. Read more at moduvalves.com.

Something happened to valves.

Never before have there been so many types of valves, dimensions, connections and spare parts. Why we built a modular system, in our own words.
