Feedback system for hand valves VPI

Overview
The VPI provides real-time position feedback of manual multiturn valves. It detects open and closed positions and transmits discrete signals to control systems (DCS), delivering up-to-date valve status to improve process control and support correct line-up procedures.

Key product information
The indicator is engineered for gate, globe and rising-stem valves. It features a universal mounting bracket, integrated terminal blocks and accessible setting inlets. The enclosure can accommodate selected sensors or switches and be combined with external junction boxes when needed.

Features

• Detects open and closed valve positions and outputs discrete signals to control systems.
• Real-time valve status suitable for DCS integration.
• Universal mounting bracket compatible with multiple valve types.
• Integrated terminal blocks and quick-connect terminals for simplified wiring.
• Accessible setting inlets for easy configuration and commissioning.
• Available in durable materials and protective coatings for harsh environments.

Configurations

• Wired — direct integration using existing cable infrastructure.
• Industrial wireless — compatible with wireless transmitters regardless of protocol.
• Mobile internet — remote communication via GPRS/mobile transmitter.

Models & Materials
The VPI is offered in coated aluminium and high-performance AISI 316 stainless steel. The product family includes VPI A-series and VPI S-series to meet different performance and environmental requirements.

Safety & hazardous area
Certain VPI A/S-series configurations are available as intrinsically safe certified solutions (ATEX and IECEx Ex i). Where the enclosure is not system-approved, the VPI can house certified components or be used with an external junction box to meet hazardous-area requirements.

Benefits

• Improves process performance and reduces risk of incorrect valve line-ups.
• Provides centralized, current valve status for operators and control systems.
• Rugged design suitable for industrial field conditions.
