Butterfly Valves Manufacturers and Supplier

PRODUCT FEATURES :

• VALCO SLIM SEAL, WAFER DESIGNED BUTTERFLY VALVES ARE LOW TORQUE, QUARTER TURN, BI DIRECTIONAL ROTARY VALVES.
• BUTTERFLY VALVES ARE MOST ECONOMICAL VALVES FOR FLUID ISOLATION APPLICATIONS
• THESE VALVES VERY THIN IN SIZE & ARE WIDELY PREFERRED & USED IN ALMOST EVERY INDUSTRY FOR VARIOUS APPLICATIONS.
• BUTTERFLY VALVES ARE SIMPLE EASY TO INSTALL & OPERATE.
• THESE VALVES ARE USED FOR AIR / WATER MEDIA IN GENERAL BUT ALSO PREFERRED FOR VARIOUS OTHER MEDIAS LIKE POWDER / CEMENT / COAL /FLY ASH ETC
• PROPER SELECTION OF RUBBER / MOC OF PARTS BECOMES IMPORTANT WHILE SELECTING VALVES FOR APPLICATIONS OTHER THEN AIR / WATER AS COMPATIBILITY OF SEALING RUBBER & DISC IS AN IMPORTANT CRITERION FOR VALVE SELECTION FOR VARIOUS MATERIALS & TEMPERATURES.CONSULT WITH DETAILED DETA INFORMATION FOR RIGHT SELECTION OF SUITABLE VALVES

PNEUMATIC OPERATED VALVES

PNEUMATIC ROTARY ACTUATOR OPERATED :

• VALVES CAN BE REMOTELY OPERATED WITH PNEUMATIC ROTARY ACTUATORS.
• ROTARY ACTUATORS ARE HEAVY DUTY RIGID ACTUATORS OPERATED WITH RACK & PINION MECHANISM.
• ACTUATORS CAN BE DOUBLE ACTING & SINGLE ACTING TYPE.
• SOLENOID VALVES WITH REQUIRED SUPPLY VOLTAGES CAN BE SUPPLIED FOR ACTUATORS
• DOME TYPE LIMIT SWITCH BOX CAN BE USED FOR VALVE OPEN / CLOSE FEEDBACK TO PLC
• FOR MODULATING VALVE CONTROLS, VALVE CAN BE OPERATED WITH PNEUMATIC / ELECTRO- PNEUMATIC POSITIONERS WITH CONTROL SIGNALS OF 3 TO 15 PSI OR 4-20 MAMPS
• ACCESSORIES LIKE AFR UNITS / MATCHING FLANGES ETC ALSO PROVIDED WITH VALVES
• SPECIAL VALVES FOR FILLING APPLICATIONS ARE PROVIDED WITH REQUIRED SOV
• SIZE & RANGE OF PNEUMATIC ACTUATOR VALVES :

PNEUMATIC CYLINDER ACTUATOR OPERATED VALVES :

• WE ARE AMONG MFGS OF PNEUMATIC CYLINDER OPERATED BUTTERFLY VALVES.
• THESE VALVES OVERCOME THE LIMITATIONS OF ACTUATOR OPERATED VALVES
• VALVES ARE SUITABLE HIGH FREQUENCY OPERATIONS
• SOLENOID VALVES WITH REQUIRED SUPPLY VOLTAGES CAN BE SUPPLIED FOR ACTUATORS
• DOME TYPE LIMIT SWITCH BOX CAN BE USED FOR VALVE OPEN / CLOSE FEEDBACK TO PLC
• FOR MODULATING VALVE CONTROLS, VALVE CAN BE OPERATED WITH PNEUMATIC / ELECTRO- PNEUMATIC POSITIONERS WITH CONTROL SIGNALS OF 3 TO 15 PSI OR 4-20 MAMPS
• ACCESSORIES LIKE AFR UNITS / MATCHING FLANGES ETC ALSO PROVIDED WITH VALVES
• SPECIAL VALVES FOR FILLING APPLICATIONS ARE PROVIDED WITH REQUIRED SOV
• SIZE & RANGE OF PNEUMATIC ACTUATOR VALVES :

ELECTRIC ACTUATOR OPERATED BUTTERFLY VALVES

• VALVES CAN ALSO BE EQUIPED WITH ELECTRIC ACTUATORS.
• ELECTRIC ACTUATOR OPERATED VALVES TAKES MORE TIME TO OPERATE COMPARED TO PNEUMATIC ACTUATED VALVES
• CONSTRUCTION IS BULKY COMPARED TO PNEUMATIC VALVES
• THESE VALVES ARE SUITABLE FOR LOCATIONS WHERE PNEUMATIC SUPPLY PROVISION IS NOT POSSIBLE
• VALVES CAN BE SUPPLIED WITH FEEDBACK LIMIT SWITCHES FOR VALVE OPEN / CLOSE FEEDBACK
• ACCESSORIES LIKE AFR UNITS / MATCHING FLANGES ETC CAN ALSO BE PROVIDED WITH VALVES
• SIZE & RANGE OF PNEUMATIC ACTUATOR VALVES :
