DIVAL regulator 500 MP block of max. and min. 300mbar 1"

The pressure regulators of the DIVAL 500 series are direct action regulators with balanced obturator, membrane control and spring contrast action, suitable for low, medium and high pressures. The DIVAL series regulators are factory supplied for operation with only the internal impulse take-off, both regulator and slam-shut valve. The regulator and block are set up for connection of the external impulse take-off (by the customer) in relation to the flow rate tables, following page. They are widely used in both civil and industrial installations that use NG or LPG or non-corrosive gases. Thanks to the balanced obturator design, the following is obtained: • high flow rate coefficient • high regulation precision even at maximum flow rates • closing pressure zone and pressure closing pressure, relatively reduced • reduced response times • hermetic closure with zero required flow rate • reaction type on opening (fail to open) • possible periodic maintenance without disassembling the body from the pipes • possibility of incorporating the slam-shut valve (model LA only ) even on regulators already installed without any modification of the piping.
