Description
AQ MATIC K53 Series Control Valves
Corrosion-resistant construction withstands harsh media
Features and Benefits
- 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; and only normal cost for spring assist opening for low-pressure and self-draining applications
- 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**
- Two dynamic O-rings on the shaft, with a vent in between the O-rings, to prevent damage to the diaphragm
- Female socket weld connectors for easy installation and the ability to remove the valve without disrupting the service piping
- Valve bodies provided with molded pads that can be used to support the piping manifold
- Cap held by a retaining ring, eliminating screws and nuts; no external metal parts to corrode in aggressive environment
- Available in sizes from 1″-3″
- A variety of end connectors are available to make the valve compatible in pipe sizes from 3/4″-3″
- Adaptable to a wide variety of control devices
Options
- Normally open [standard]
- Externally normally closed
