The pressure regulators of the DIVAL 500 series are regulators of the direct action type with balanced shutter, diaphragm control and contrast action with spring, suitable for low, medium and high pressures.The DIVAL series regulators are supplied from the factory for operation with only the internal impulse socket, both regulator and block valve.The regulator and lock are designed for connection of the external impulse socket (by the customer) in relation to the flow tables, next page. They are widely used in both civil and industrial installations that use G.N. or G.P.L. or non-corrosive gases.Thanks to the design with balanced shutter it is possible to obtain:• high flow coefficient• high regulation precision even at maximum flow rates• relatively low closing pressure and closing pressure zone• reduced response times• hermetic closure with zero required flow rate• fail-to-open reaction type• periodic maintenance possible without removing the body from the pipes• possibility of incorporating the shut-off valve (model LA only) also on regulators already installed without any modification of the pipes.
