Vahn-Tech International Inc. products

CanLeaf Advanced design with simple mechanism along with strong float to prevent cracking during sudden water hammer & quick closure. CanLeaf Aerokinetic mechanism to resist blow shut under high air velocity even up to sonic velocity of air. CanLeaf For the potential water hammer area or transmission pipeline, it is recommended to use anti-shock combination air valve to prevent from damage or impact of severe water hammer. CanLeaf Anti-shock device is installed on top of bonnet, it will slow down the exhausting air flow during filling to prevent hammer impact, under vacuum condition, the device will drop down and let large air into the pipeline.

Main valve uses globe design for superior control characteristic. CanLeaf Top and Bottom seat rings are used to guide the stem and diaphragm assembly for extended life time and stability. CanLeaf High strength ductile iron body used for lowering the weight and improving long term durability. Stainless steel used for seat and disc retainer ring for corrosion resistance. CanLeaf Easy maintenance without having to remove valve from the main line. CanLeaf Nylon reinforced rubber diaphragm for long term service. Drop tight shut-off capacity. CanLeaf Various pilots and accessories available to offer a large range of control applications. CanLeaf All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance per AWWA C550. CanLeaf Meet standards BS EN 1074-5, ISO 5208, BS EN 12266-1, BS EN 558-1, BS EN 1092-2.

Metal Seated Gate Valves fully meet or exceed AWWA C500 and MSS SP 70 standards. CanLeaf High strength ductile iron body used for lowering the weight and improving long term durability. CanLeaf All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance per AWWA C550. CanLeaf Design with solid wedge and bronze trim to reduce wear and tear. CanLeaf Upper O-Rings are replaceable with valve fully open under operating pressure. CanLeaf ANSI B16.1 Class 125 and ANSI B16.5 Class 150 flanges are both available. Mechanical Joints connection available as option. CanLeaf NSF61 & NSF732 certified for Drinking Water. CanLeaf UL Listed Valve.

CanLeaf High strength ductile iron body used for lowering the weight and improving long term durability. CanLeaf Advance dynamic design of single body with diffuser provides streamline flow and assures lower head loss. CanLeaf One of the lowest head loss check valve, resulting in savings towards power costs, valve disc with shorter plunger and spring reverse faster than most of check valve. CanLeaf All iron parts are coated inside & outside with fusion bonded epoxy for corrosion resistance per AWWA C550. CanLeaf Bronze bushing reduce wear and tear.

CanLeaf High strength ductile iron body used for lowering the weight and improving long term durability. CanLeaf Valves can be used for isolation or throttling application. CanLeaf Double eccentric design butterfly is used for lowering the friction between the disc and the seat. CanLeaf Dovetail seat design with multiple raised ring is used to increase contact with the disc while loweringfriction during closure. Seat is fixed using epoxy resin based adhesive.

The plug is made of Ductile Iron and fully encapsulated with EPDM or NBR rubber, providing leakage tight sealing and making it suitable for vacuum working conditions. Thanks to the encapsulation, the plug is alsofully protected against corrosion. The abrasive particles are prevented to enter the bearing area bycompression between the rubber and the PTFE thrust gasket. CanLeafAn overlay with minimum 90% pure nickel is welded over the seat area for long term corrosion resistanceand improved tightness over the plug valve life. CanLeafThe stem seal design is self-adjusting. It is isolated from the plug stem and external torque device and isunaffected by pressure variations.

VAHN-TECH DC Series knife gate valves are linear shut off valves that are light weight with compact construction. Valves are available as manual with handwheel, or can be automated with pneumatic cylinder or electric actuator for remote operation. The arc shape of the gate of our knife gate valve is designed to be particularly suitable for cutting off fluid containing fiber or suspended particles. The knife gate valves are ideal for many applications in the process industries of Pulp & Paper, Wastewater Treatment, Mining, Sugar Making and Chemical Process.

VAHN-TECH offers a large range of configurations of API 602 Forged Gate Valves: Bolted or welded bonnet, pressure seal bonnet, threaded connection, SW, BW, extended nipple, welded or integral flanges, etc.

VAHN-TECH manufactures superior cast steel OS&Y globe valves in a variety of designs, materials, trims, packing types,sizes (2” thru 18”) and pressure classes (150 thru 2500). CanLeaf Globe valves are designed in compliance with API 6D / BS 1873 / API 623. CanLeaf Full choice of bonnet available: Bolted bonnet, welded bonnet or pressure seal bonner. CanLeaf Special trim design available: Proportional trim, quick opening trim, bellow seal design, etc.

The sleeve type soft sealing plug valves are suitable for use in various kinds of pipelines with working conditions from Class 150 to Class 600 and working temperature of -29°C~+150°C in such industries as petrochemical, chemical, pharmaceutical, fertilizer, and power plant etc. to cut off or turn on the flow medium in the pipelines.
