1 1/2'' Sanitary Constant Pressure Valves AV-8 AISI-304
Application
AV-8 series constant pressure valve can ensure a stable pressure at both outlet and inlet. It is widely used in separators, heat exchangers, tank systems and other equipments. It also can be used as a relief valve.
Working Principle
Constant pressure valve is remotely operated by compressed air. The operation does not need any sensors; it only requires an air pressure regulator and a pressure gauge on pipeline for monitoring. A unique plunger design can make a rapid response to any pressure changes during the medium flow and changes stem position relatively to maintain the pre-set pressure. When the pressure increases, the valve opens; when the pressure decrease, the valve closes.
Design Standard
- AV-8 series constant pressure valve complies with DIN, 3A and ISO standards.
- The valve includes a valve body with seat, valve bonnet, a stem with a diaphragm and a clamp.
- Constant pressure regulating valve's inlet is 90° angle to the valve bottom, so as to minimize residue and facilitate cleaning. The plunger design allows less liquid flow and higher CIP flow.
Technical Specification
Nominal Pressure:
Max. product pressure: 87psi (6bar)
Temperature:
Max. sterilization temperature: 130°C, dry steam: 121°C (2bar).
Steam must be dry, because condensed water will damage the diaphragm. The diaphragm should be replaced after 100 times samplings or sterilizations.
