1 1/2" Tri-Clamp Sanitary Pressure Relief Valve (CIP Manual Override)
Pazzini 900 Series
Tri-Clamp® Pressure Relief Valve (CIP Manual Override)
Pressure Relief valve is a hygienic manually adjustable valve used in the food, beverage and processing industry applications where over pressure must be discharged in order to avoid damage to plant and / or personnel
Features:
• Manual operated in order to open during the clean-in-place (CIP) .
• Made in SS316L / wetted surfaces
• Manually adjustable from 10 to 150 psi
• The specific pressure is set by adjusting the spring pressure nut.
• Seat gasket replacement in less than 10 minutes without removing the valve from the line and no tools required.
Materials:
• Product wetted steel parts: AISI 316L (internal Ra < 0.8 μm)
• Other parts in stainless Steel: AISI 304
• Plug gasket: EPDM
• Other product wetted seals EPDM (standard)
Technical specifications:
• Max working pressure: 145 psi (10 bar)
• Min. working pressure: Full vacuum
• Working temperature: Please see below information.

Flow Capacity:
The flow coefficient Cv is the volume (in US gallons) of water at 60 °F that will flow per minute through a valve with a pressure drop of 1 psi across the valve.

1 1/2" | 50 |
For other pressure drops than 1 psi the flow can be calculated with the following formula:
Q= Cv x √ ∆p
Where:
Q= Flow in GPM
Cv = Flow coefficient.
∆p = Pressure drop in psi over the valve.
Example:
1 1/2" valve has a Cv= 50 GPM with a pressure drop of 1 psi.
For a pressure drop of 2 psi which is the flow?
Q= 50 X √2 = 71 GPM.
