Description
AQ MATIC K55 Series Composite Control Valves
Constructed of corrosion-resistant materials
Features and Benefits
- The unique Y-pattern design with large seat opening and high lift disc permits higher flow rates at lower pressure loss than other comparable valves
- All components can be serviced while the valve is in-line
- Separate flow and control chambers permit positive closing without springs
- Pre-formed, stress-relieved diaphragm minimizes fatigue, maximizes valve responsiveness and diaphragm lifetime
- Diaphragm acts as an actuator, eliminating the need for electric or pneumatic actuators
- All internal parts in contact with media are made of composite materials
- Seals are ethylene propylene for better chemical resistance*
- K55 Series Valves are available in sizes from 1/2”- 2”A variety of available end connectors make the valve compatible for 3/8”-3” pipe sizes
- Adaptable to a wide variety of control devices
- Isolated bonnet Assures no cross connection between line & control fluid
Options
- Normally open [standard]
- Limit stop for flow control
- Seal and diaphragm materials for special applications
- Union End Connectors – Female socket weld connectors for easy installation and the ability to remove the valve without disrupting the service piping
- Failsafe spring closed 30, 60, and 100 PSI
Typical Applications
- Chemical Injection
- Deionizers
