VRC Valve Related Controls from John Brooks Company

VRC Valve Related Controls have been manufacturing quality American made products for over 30 years. There are hundreds of thousands of applications worldwide that have VRC units in their facilities providing solid trouble free service after 5-10-15 years and longer. In addition to being durable the VRC positioners are calibrated prior to shipment and due to the stable design generally never require any routine recalibration or service.

VRC Valve Related Controls Features

Modular:  Modularity is the cornerstone of the entire VRC line. Upgrading or modifying any unit is simple, quick and hassle-free. Switch from pneumatic to electro-pneumatic with ease. Upgrade a positioner in the field with Limit Switches and position Transmitters easily. VRC simplifies upgrades, minimizes inventory and eases servicing like no other line on the market.

Corrosion Resistant:  VRC corrosion resistance is unequaled. The I/P Converter and Position Feedback Transmitter are epoxy sealed and the Proximity Switches are hermetically sealed for the ultimate environmental protection. The PPA enclosure and internals exceed NEMA standards and are specifically designed for all routine and most highly corrosive applications. The PPA enclosure is inherently waterproof and carbon graphite filled to satisfy the toughest demands in both indoor and outdoor applications.

Easy to Mount:  Adaptability is a key feature of the V Series. Regardless of actuator model or design, the option V Series Universal Mounting Kit allows for customized adaptation to most current industry models, sizes and styles of quarter turn actuators. The low profile design of the V Series Universal Mounting Kit insures high performance adaption to the accessory side of the actuator.

	VP Model General Purpose Pneumatic Valve Positioners The VP Model General Purpose Pneumatic Valve Positioners use a 3 – 15 psi input control signal to control valve or damper position. Many options are available to the basic unit to provide flexibility for your application. Positioner and options are designed for easy field installation. The base unit can be reconfigured to accommodate changes in your ongoing control needs, protecting your initial investment.
	VE Model General Purpose Electro-Pneumatic Valve Positioners The VE Model Pneumatic Valve Positioner uses a 4 – 20 milliamp input control signal to control valve or damper position. Many options are available to the basic unit to provide flexibility for your application. Positioner and options are designed for easy field installation. The base unit can be reconfigured to accommodate changes in your ongoing control needs, protecting your initial investment.
	VI Model General Purpose + Hazardous Locations Electro-Pneumatic Valve Positioners The VI Model Pneumatic Valve Positioner uses a 4 – 20 milliamp input control signal to control valve or damper position. Many options are available to the basic unit to provide flexibility for your application. The VI Model is designed for general purpose as well as hazardous locations. Positioner and options are designed for easy field installation. The base unit can be reconfigured to accommodate changes in your ongoing control needs, protecting your initial investment.
	VX Model Hazardous Locations Electro-Pneumatic Valve Positioners The VX model valve positioner incorporates a manifold mounted, 4 – 20 milliamp input, I/P that is approved for use in hazardous areas. MODEL VX – Hazardous Locations Information Note: For the VX model hazardous ratings apply to the I/P metal (NEMA 7) housing only, the positioner housing is NEMA 4x only
	VF Model Fail-Freeze I/P Electro-Pneumatic Valve Positioners The VF model valve positioner incorporates a manifold mounted, 4 – 20 milliamp input, I/P. The VF model can be used where you require the control valve to fail in position (Fail Freeze) on loss of the 4 – 20 milliamp input signal.
