Operating principle

• Under normal operating conditions,the valve remains closed.
• The specific pressure is set by adjusting the spring with the pressure nut.
• When the pressure in the pipes is above the specific pressure,the valve becomes open automatically to make the liquid pass over in order to reduce the pressure in the pipes.
• The valve can be with handle in order to realize partial open.When the handle remains open on the operation spot,the detergent can flow though the flow valves.

Technical specifications

• Max. temperature121℃(EPDM)/250°F
• Max. operating pressure :Spring  adjustable (0-3bar/0-6bar/0-10bar)/(0-43,5PSI/0-87PSI/0-145PSI)

Materials

• Product wetted steel parts : 304/316L
• Other steel parts :3 04
• Spring steel parts : 60 Si2Mn
• Flow components of surface roughness : Ra≤0.8um
• Outer surface roughness : Ra≤0.8um
• Wetted seals : EPDM(standard items)
• Other Seals : PTFE, EPDM

Options

• Connections DIN-IDF-RJT-3A-SMS,Clamp,flanges,Welding,Threded.
• Material of gasket : EPDM NBR FPM
• Pressure Ranges (changing the spring).
• The assembly with handle can open the valve partially.When CIP (with use of pump passes),the liquid can be flowed though.
