Operating Specifications

Maximum Pressure: 125 psi (8.6 bar)
Maximum Temperature: 140°F (60°C)

Operation
Close by introducing either hydraulic or pneumatic pressure to the upper diaphragm chamber. 
The control pressure must be equal to or greater than the line pressure. 
The valve is opened by relieving the pressure from the upper diaphragm chamber. 
The line pressure under the seat will then open the valve. 
The unique y-pattern design minimizes pressure loss in the valve.

Features:

• 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
• Cap held by a retaining ring, eliminates screws and nuts
• No external metal parts to corrode in aggressive atmosphere
• Valve bodies provided with molded pads can be used to support piping manifold
• Reinforced diaphragms are pre-formed and stress relieved to maximize responsiveness and product life
• Ideal for corrosive applications including deionized water, acids, caustis and harsh chemicals that would rapidly corrode metal valves
• Can be actuated with either air or water as control fluid
