AquaMatic ® Diaphragm Valves
The AquaMatic Y pattern diaphragm valve, with
large seat opening and high lift disc, permits
greater flows at lower pressure loss than any
comparable valve. Positive control action is
achieved, either hydraulically or pneumatically,
without the aid of springs. And, components are
serviceable while the valve is in line. These valves
are available in both metal and thermoplastic
materials, and are ideal for fluid treatments and
handling systems.
Features and Options
• Lowest pressure loss
Y pattern permits higher flows at lower pressure
loss than any comparable valve.
• Positive control
Separate flow control chambers permit positive closing without springs; and only nominal cost for spring assist
opening for low pressure and self-draining considerations.
• Cost effective
Both initially and in lifetime maintenance.
• Extended diaphragm life
Separate chamber protects diaphragm from flow stream; allows replacement without disrupting service.
Performed, stress-relieved diaphragm minimizes fatigue, maximizes valve responsiveness and diaphragm
lifetime.
• Durable
Cast iron, brass, bronze, stainless steel, and engineering thermoplastic components. Average maintenance-free
life of three to five years and longer dependent upon cycling rate and environment.
• Design/application engineering service
• Optional seal and diaphragm materials for special applications
• Handles liquids or gases
• Adaptable to a variety of control devices
• Optional adjustable flow rate control
• Optional spring assist
• Optional position indication
The diaphragm valves are available in both metal and thermoplastic materials - each with a variety of design
configurations and features that meet hundreds of fluid property and control requirements:
Standard, metal body valves • High pressure valves • Standard, plastic body valves • Solenoid operated valves
• Float operated valves • High temperature valves (Isolated bonnet) • Fail-safe close valves
