PNEUMATIC BUTTERFLY VLAVES
The wafer butterfly valve is much smaller than other valve designs. The results are savings in materials, less weight, small space requirement, and ease of installation and operation. Wafer construction provides maximum strength under conditions of pipeline strain. Less torque, less time for opening (closing), compact, maintenance-free, bubble tight seal, long life, reliable performance and less cost for these entire outstanding features-this is butterfly valve.
The resilient seat of the butterfly valve performs several functions; forms a drop-tight seal with the disc, serves as the gasket between the flange and valve faces, and isolates the valve components from the flowing media. The result is rugged simple construction and little or no maintenance.
FEATURES
- · COMPACT SIZE & LIGHT WEIGHT
- · LONG SERVICE LIFE & LOWER COST
- · SIMPLE INSTALLATION & MAINTENANCE
- · PNEUMATIC CONTROL OPERATION
- · PERFECT CUT OFF
- · VERSATILE FUNCTION
- · WIDE APPLICATION
- · SAVE 8-WAYS WITH BUTTERFLY VALVES
-
- 1. Initial Cost
Lower than equivalent gate, globe, ball, plug valves. Enveloping seat means economical body & shaft materials can be used.
- 2. Installation
Compact size lightweight and flange locating holes drilled to flange specification required bring new ease of valve installation.
- 3. Space
16protage the space of an equivalent cast iron gate, ball, globe, plug valve
- 4. Weight
11protage the weight of an equivalent cast iron other valves.
- 5. Maintenance
Simple construction means “Install it and forget it” service. Free service
- 6. Protection
Body and shaft are completely protected from line media by the seat. Rugged construction means trouble-free service.
- 7. Investment
The increasing trend to butterfly valves means freedom from obsolescence.
- 8. Versatility
Same valves may be used for on-off or throttling control. Wide choice of manual.
Pneumatic, electric, and hydraulic actuators and Accessories fill every requirement.
