Usage

The orifice plate must be used for pressure reduction in Sinorix ™ extinguishing systems only. It is installed

between orifice plate holders fitted to the end of the manifold to reduce the pressure developed in the distribution

pipework from the cylinder pressure (300 bar) to the calculated pipe pressure (normally 60 bar).

Safety warning This product information is exclusively intended for specialized operators with the experience in designing, mounting, installing, commissioning, maintaining and retrofitting fire extinguishing systems. The user must ensure that the part is not abused an only used within its design limits and that all danger to life and limb of the operator, or third parties, is avoided. Moreover, compliance must be ensured with accident prevention regulations and national regulations.

Procedure 1. Check that the O-rings are fitted to the orifice holders and are free from any damage. 2. Lubricate the O-rings. Use petroleum jelly (Vaseline) or similar grease. 3. Install the orifice plate between the orifice holders, in the direction of flow (marked on the orifice plate) as shown in the following drawing. 1 2 3 4 5 6 1 4 6 5 2 5 Orifice holder at the inlet side.

Maintenance The orifice plate itself is maintenance-free. After an extinguishant discharge: · Check that the orifice holder screws are tight. Service inspection requirements: · Check the pipework for any unauthorized modifications which may result in a change of orifice diameter. · Check the orifice holders for any damage or corrosion. · Check that the orifice holder screws are tight. Warning! Any defective parts must be replaced immediately.

Drilling instructions max. 0.2x45° max. 0.2x45° Requirements · The orifice must be drilled correctly, so it corresponds with the coefficient of the VdS calculation software. Failure to drill the orifice correctly will affect the discharge time of the system and the pressure developed in the downstream pipework, which may exceed the maximum working pressure rating for the pipe and fittings. · Orifice plates are normally supplied drilled to the correct diameter and supplied with the equipment.
