Need Expert Invensys & Robertshaw Sourcing?

Schneider Electric’s legacy building controls portfolio—encompassing Invensys, Robertshaw, and Erie Controls—forms the backbone of mechanical control in thousands of commercial and industrial facilities. Because these legacy valves, actuators, DDC controllers, and zone controls rely on specific signal ranges, thread geometries, and linkage kits, finding exact matching replacements requires complete technical accuracy. Contact our dedicated building automation sourcing team today to locate your specific replacement valve body, motor actuator, room sensor, or electropneumatic transducer.

Worked Examples: Decoding Invensys Catalog Numbers

Invensys, Robertshaw, Erie, and Schneider Electric part numbering follows a position-based alphanumeric framework that specifies body style, pipe size, flow coefficient ($C_v$), electrical requirements, and internal seal materials. Review our technical worked examples below.

Bronze Two-Way Globe Valve Body

• VB-7213-0-4-04 — 3/4″ NPT Stem-Up Open Bronze Globe Valve

VB (Valve Body Product Class) • 721 (Two-Way Stem-Up Open Body Pattern) • 3 (Bronze Body, Threaded NPT Connections) • -0 (Standard Single-Seat Plug Configuration) • -4 (3/4″ Nominal Pipe Size) • -04 (4.4 $C_v$ Flow Coefficient Rating)

Spring-Return Hydraulic/Electric Actuator

• MP-5210-000 — Proportional Spring-Return Actuator for Globe Valves

MP (Motorized Positioner / Actuator Class) • 5210 (Proportional Hydraulic/Electric Drive Mechanism, 120 VAC, Spring-Return Fail-Safe Action) • -000 (Standard Internal Transformer and Base Interface Configuration)

Electropneumatic Signal Transducer

• CP-8511-024 — Electronic-to-Pneumatic Transducer

CP (Control Pneumatic Component Identifier) • 8511 (High-Volume Electropneumatic Transducer Series converting 4-20 mA or 0-10 VDC inputs into 3-15 psi output) • -024 (24 VAC Operating Input Voltage)

Building Automation Sourcing Tip: When retrofitting older Invensys, Robertshaw, or Erie valve assemblies (such as replacing an aging MP-5210 actuator), you do not necessarily need to drain the hydronic system and cut out the VB-7000 valve body. Modern Schneider Electric SmartX (SpaceLogic) actuators can be mounted directly onto legacy VB-7000 bodies using standard linkage adapter kits (like the AV-390 or AV-400 series). This saves significant labor costs and eliminates piping downtime.

Invensys & Robertshaw Building Controls FAQ

Understanding brand consolidation, actuator replacement paths, and signal conversions is essential for maintaining legacy facility controls. Review our expert hardware support answers below.

What is the history behind Robertshaw, Invensys, Erie, and Schneider Electric?
Over several decades, major building control lines consolidated under unified corporate umbrellas. Robertshaw Building Controls, Erie Controls, and Invensys Building Systems were brought together through a series of integrations that ultimately formed part of Schneider Electric. Today, these historical product lines are integrated into Schneider Electric’s EcoStruxure and SmartX building automation ecosystem. TCI Supply maintains inventory across all of these brand iterations to support repair-in-place service.

Are legacy Invensys and Robertshaw VB-7000 globe valve bodies compatible with new actuators?
Yes. The VB-7000 series globe valve design has remained remarkably consistent across the Invensys, Robertshaw, and Schneider Electric eras. Modern Schneider Electric SpaceLogic actuators (or third-party actuators like Belimo) can be adapted to legacy VB-7000 bodies using standard linkage kits, allowing you to replace a failed actuator without disturbing the plumbing.

How do I replace a legacy Invensys or Robertshaw MP-5210 or MA-series actuator?
Direct-fit replacement MP-5210 and MA-series actuators are available through TCI Supply for exact repair-in-place service. If modernizing, current-generation electronic linear valve actuators from Schneider Electric can cross-reference to these older models. Key factors to match include stroke length, stem force (lb-force), operating voltage (24 VAC vs 120 VAC), and control signal type (2-10 VDC, 4-20 mA, floating, or two-position).

What is a CP-8511 electropneumatic transducer used for?
The CP-8511 (and related CP-8551) converts an analog electronic signal from a DDC building automation system (typically 4-20 mA or 0-10 VDC) into a proportional pneumatic output pressure (typically 3-15 psi). It serves as the vital bridge component in hybrid systems where modern digital controllers govern pneumatic actuators on large steam valves or air handling dampers.

Are MicroNet room sensors (MN-S1, MN-S3) still available for replacement?
Yes. TCI Supply carries MicroNet series wall sensors (MN-S1, MN-S2, MN-S3, MN-S4, MN-S5) and controllers (MN300, MN400, MN-VAV). These units communicate over the U-channel sensor link to MicroNet controllers. Because room sensors are subject to physical wear and damage in occupied spaces, having exact replacement units on hand preserves zone control without requiring reprogramming or controller replacements.
