Fully Automatic Safety Valve Vacuum Relief Air Inlet Valves

Production Description:
Pressure Relief Valves are the last resort when abnormal pressure conditions endanger the silo structure. This is why sudden excess or suction pressure inside the silo must be dealt with instantaneously. Even though ideally a Pressure Relief Valve should never have to go into action, it must be efficient and reliable if needed.
With hundreds of thousands installed worldwide, VCP Pressure Relief Valves have given evidence of being totally reliable under most different conditions.
For applications in the food industry a version compliant with European Regulation (EC) No. 1935/2004 is available.

Feature:

1. Water-proof--Stainless steel/ Engineering plastics
2. valve plate-- Carbon steel / Stainless steel,  Black special sealing rubber mat 
3. Valve body-- Carbon steel surface coating/ Stainless steel
4. Connection--Flange connection,  With gasket, embrace hoop connection, With seals 

Function:
Helical springs keep the valve lids closed when the pressure value remains within the preset limits. The three outside spring rods keep the external ring-shaped lid firmly closed as long as the force generated by the pressure inside the silo does not overcome the spring force. Once the pressure exceeds the pre-set value the lid is pushed up and pressure can escape. The smaller lid covers the central circular opening of the external lid from below. It is held in the middle by a single spring rod and is pressed onto the external lid by the normal air pressure inside the silo. In the event of suction pressure the spring is compressed and allows the lid to drop. The air entering the silo from outside ensures rapid pressure balance and pushes the central lid back up into "closed" position.
For applications in the food industry a version compliant with European Regulation (EC) No. 1935/2004 is available.


Operations:

• ATEX-certified version
• Compliance with European Regulation (EC) No. 1935/2004
• Optionally different settings available
