AquaMatic V46 Series Diaphragm Valves are constructed of stainless steel and designed for water applications. Their unique Y-pattern design with a large seat opening and high lift disc permits higher flow rates at lower pressure loss than competitive valves. This product is manufactured in the United States of foreign and domestic parts.

Features and Benefits
•
Larger diaphragm area than seat area permits drip-tight closing without any springs
•
All components can be serviced while the valve is inline
•
Separate flow and control chambers permit positive closing without springs
•
Reinforced diaphragms are pre-formed and stress relieved to maximize responsiveness and product life
•
Diaphragm acts as actuator, eliminating need for electric or pneumatic actuators
•
Durable stainless steel [CF8M] corrosion-resistant alloy, all metal internal parts machined from 316 stainless steel alloy
•
Available in 1 to 2 inch sizes with either threaded (NPT) or flanged (ASTM) ends
•
Adaptable to a wide variety of control devices
Certified by IAPMO R&T to NSF/ANSI 61 and NSF/ANSI 372 for lead free compliance.

Principles of Operation
DRIP-TIGHT CLOSING: Closure is obtained by directing line pressure or equivalent independent pressure into the upper chamber. This pressure on the large diaphragm area causes the valve disc to seal against the seat.
FULL OPEN OPERATION: When the closing pressure in the upper chamber is relieved by venting the pilot line, the valve opens positively, by line pressure on the disc.
