Series P60-M1
Miniature Plastic Water
Pressure Regulators
Size: 1⁄4" (8mm)
Series P60-M1 Miniature Plastic Water Pressure Regulators
are ideal for applications where a small economical package is
required. This series is also suitable for deionized water. Series
P60-M1 features a balanced piston design for applications
where a constant downstream and accurate flow performance
is required.
Features
• Corrosion resistant thermoplastic body
• Compact design and lightweight construction
• All external components are made of NSF approved
thermoplastics
• All internal rubber components such as disc, diaphragm and
seals are all FDA grade elastomers
• All internal metal components in contact with fluid are of 300
series stainless steel
• Straight through or 90º inlet to outlet option (suffix 4 option)
• High capacity
• Bottom "clean out plug" for service
