These electrically actuated valves shut off oil lines in less than one second. A variety of optional body materials and body connections provide reliable operation of these shut off valves even for highly corrosive fuels and for oxygen with long-lasting metal-to-metal seating. Application flexibility is provided with 3/8" through 2" diameter line sizes, Cv flow factors up to 218, and line pressures up to 600 PSIG.

These electrically actuated valves shut off gas or oil lines in less than one second. All shut off valves come equipped with long-lasting metal-to-metal seating. A variety of optional body materials and body connections provide reliable operation even for highly corrosive fuels and for oxygen. Application flexibility is provided with 3/4" through 6" diameter line sizes, Cv flow factors up to 1230, and line pressures up to 125 PSIG. .

Series 8000 Air Actuated Shut Off Valves combine a unique space-saving design with a maintenance-free bonnet seal and a replaceable actuator for easy installation and smooth, trouble-free operation. This gas valve's quick exhaust and powerful closing spring provide valve closure in less than one second and reliable, long-life operation. Valve seats are micro-lapped metals. These gas valves ensure positive sealing with our trademark durability.

Unlike other pneumatic valves, these valves require no maintenance. More importantly, these seats require no regular tightening of valve packings like ball valve designs The Series 8000 Valve has been FM and CSA rated for hazardous locations

Style Synchro flow control valve bodies are designed to meet ANSI flange specifications. High pressure rating flow control valves are available in cast iron, carbon steel and brass bodies. SYNCHRO Gas Valves may be used independently for individual adjustable gradient fuel flow control, or in tandem with other fuel and air control valves for more sophisticated multi-zone control or multi-fuel applications.

These air actuated valves shut off gas or oil lines in less than one second and the Series 1000 and Series 2000 are approved for General Purpose and Hazardous Duty locations by FM (Factory Mutual) and CGA (Canadian Gas Association) Powerful spring-loaded air operators permit much higher differential pressure ratings

Series "CV" Flow Control Valves incorporate a full-flow, fixed gradient butterfly valve design for high capacities at low pressure drops, using minimum operating torque. Series "BV" Balancing Valves are used to balance gas or air flows in multiple-burner systems fed by a common manifold. These gas valves feature a full-flow butterfly design with provision for locking in any position. Both flow control valves are used for air, gas and oil proportioning control.

Used for air, gas and oil proportioning control, the MICRO-RATIO® Oil and Gas Valve assemblies have a multiple screw cam assembly. This oil flow valve's assembly provides mechanical adjustment capabilities to the air/fuel ratio at each valve position throughout the entire capacity range of your burner system. This gas valve provides a fully adjustable throttling range and is designed to operate over the extremely wide turndown capabilities of modern industrial burner systems.

These electrically actuated valves shut off gas or oil lines in less than one second. Normally open versions of these shut off valves are available for vent or process purge lines with long-lasting metal-to-metal seating. A variety of optional body materials and body connections provide reliable operation of the gas valve even for highly corrosive fuels and for oxygen. Application flexibility is provided with 3/4" through 6" diameter line sizes, Cv flow factors up to 765, and line pressures up to 125 PSIG.

SMARTFIRE® is a turnkey, mass flow air/fuel ratio control system for use with natural gas and oxygen fired burners, especially those designed for low-emission applications like our KINEDIZER®, CYCLOMAX®, OXY-THERM® industrial burners. The flow control valve system is comprised of five omponents that integrate easily with a conventional burner management system and pipe train. The SMARTFIRE® System provides precise electronic control of air and fuel flow to the burner, maintaining emissions or fuel efficiency over the entire operating range of the burner. It automatically compensates for changes in combustion or process conditions with full cross-limited ratio control, maximizing burner performance and ensuring a highly repeatable heat source

These electrically actuated shut off valves vent gas reliably for block and bleed installations. All gas valves are available for vent or process purge lines with long-lasting metal-to-metal seating. Application flexibility is provided with 3/8" through 4" diameter line sizes, Cv flow factors up to 490, and line pressures up to 125 PSIG..
