Product Description

Modular Design

Modular design of pressure regulator Dival 600 series allows the installation of an incorporated slam shut or device for use as “in line monitor” on the same body without changing the face-to-face dimension.
Furthermore the truly “top entry design” allows an easy periodical maintenance without removing body from the line. The features of Dival 600 series regulators make it a product suitable for any application.
The fast response time makes it ideal for burner or industrial applications or whenever sudden changes of flowrate are part of the process.
The high accuracy against any inlet pressure variation makes of Dival 600 series an optimum product also for gas district systems, an application generally where piloted operating regulators are preferred.
An extremely easy maintenance and a reduced number of parts are the background of low cost operation. Accessories on request:
- Incorporated slum shuh-valve
- In line monitor function
- Silencer;
- Incorporated relief valve.

This is a device which stops immediately gas flow whenever downstream pressure exeeds given set-point. Device can be actuated also manually. Incorporated LA Slam shut (see figure 2) can be incorporated in the standard regulator and in the in-line monitor. The installation of integral Slam Shut valve does not produce any reduction on regulator KG or Cg values.
A further advantage of the incorporated slam-shut valve is that it can be retro fitted at any time on a previously installed Dival 600 series without modifying the regulating unit (only with 4 ways body).
Further the slam-shut can be positioned in four different positions (rotation on its axis) in such way to be fixed in the most apropriated position versus the surrounding encumbrance if any.

Proven Technology

The main features of this slam-shut device are:
- design pressure 20 bar for all the components;
- accuracy (AG): ap to 5 for pressure increase, up to 15 for pressure decreasing;
- internal by-pass;
- intervention for over pressure and/or under pressure;
- manual push-button control;
- possibility of pneumatic or electromagnetic remote control;
- compact overall dimensions;
- easy maintenance;
- possibility of application of devices for remote signal (contact or inductive microswitches).


Whenever specific noise limits are required, the silencer allows you to considerably reduce the decibel (dBA) noise emissions during the gas pressure regulators operation.
The Dival 600 pressure regulator can be supplied with an incorporated silencer in either the standard version, with incorporated slam-shut or in line monitor version.
