SENA tap series are manually operated metallic ball valves that, due to their design and materials are intended to be used in outdoor plumbing networks like gardens, terraces, etc.

In general, all those applications that require a valve to shut off the liquid flow, assuring leak tightness and fulfill all the following service conditions.

Moreover these SENA taps are able to connect a hose, so most of the models include a nozzle for that purpose.

Nominal pressure: 25 barTemperature range: Cold and hot water until 65ºCFluid: Drinking water

MAIN CONSTRUCTIVE FEATURES

BODY AND LATERAL

Main body and lateral manufactured in European brass alloy CW617N, by the mean of a hot stamping process. This process confers to the European brass alloy the following advantages against casting parts:

- Pores absence.- Surfaces with better finished and without bumpy texture.- Higher mechanical endurance.

SPHERICAL CLOSURE

Spherical closure is made in brass, ensuring a higher mechanical endurance against high pressure and maneuvers.

Its diamond mechanized and the following chrome plated applied on the ball surface assure a long lifespan and a smooth maneuver.

INTERNAL LEAKTIGHTNESS

Internal leaktightness is assured in both directions by the PTFE seat that press against the spherical closure.

EXTERNAL LEAKTIGHTNESS

External leaktighness through the stem is assured by a PTFE sealing gland allowing its retightening if necessary.

INSTALATION AND ASSEMBLY

Hold the valve from the end of connection, never from the central part or the neck of the valve in order to avoid internal components deformation, the valve colud be damaged inevitably.

The maximum lifespan of the tap is obtained with the spherical closure in full open or closed position,its is recommended to not operate in intermediate positions for long time periods.

Valves should be maneuvered every 3 months .This frequency should be increased for water with french hardness over 50º

Hydraulic features according to European norm EN 1267.
