UTILITIES & INDUSTRY Easyfit True Union ball and spring check valve

SXE-SSE DN 10÷50 EASYFIT TRUE UNION BALL AND SPRING The Easyfit check CHECK VALVE valve line developed • Connection system for solvent weld and threaded joints with Giugiaro Design • Valve material compatibility (PVC-U) with water conveyance, drinking offers two different water and other food substances according to current regulations versions: SXE with ball • PN16 True Union valve body made for PVC-U injection moulding and compliant with European Directive 97/23/EC for PED pressurised equipshutter and SSE with ment. Test requirements compliant with ISO 9393 spring loaded shutter. • Short...

Customisable Labelling System: built-in LCE module on the valve body made up of transparent protection plug and customisable tag holder using the LSE set (available as accessory). The customisation potential lets you identify the valve on the system according to specific needs Optimised dynamic fluid design: energy savings thanks to the improved valve Kv value with consequent pressure drop reduction High surface finish ball shutter: wear reduction, increase in working life and reduced valve maintenance. Ideal for conveying dirty fluids, even with suspended solids and filaments thanks to the...

TECHNICAL DATA PRESSURE VARIATION ACCORDING TO TEMPERATURE For water and harmless uids to which the material is classied as CHEMICALLY RESISTANT. In other cases, a reduction of the nominal PN pressure is required (25 years with safety factor). Pressure drop PRESSURE DROP GRAPH KV100 FLOW COEFFICIENT The Kv100 ow coefficient is the Q ow rate of litres per minute of water at a temperature of 20°C that will generate p= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the SXE valve completely open.

MINIMUM VALVE SEALING PRESSURE The PVC-U SXE valve can only be used with liquids with specic weight under 1.37g/cm3. The information in this leaet is provided in good faith. No liability will be accepted concerning technical data that is not directly covered by recognised international standards. FIP reserves the right to carry out any modication. Products must be installed and maintained by qualied personnel.

Customisation set and label printing for Easyfit handle made up of precut adhesive sheets and software for guided label creation. SXE and SSE DN 10÷50 Easyt valves are equipped with a customisable Labelling System. This system lets you create special labels to affix to the valve body. This makes it extremely easy to apply company logos, identication serial numbers or service indications such as, for example, the valve function in the system, the transported uid, but also specic information for customer service, such as the customer name or installation date or location on the valves.

SXE valves do not require maintenance in normal operating conditions. In the event of leaks or wear, before performing maintenance, cut-off fluid upstream from the valve and make sure it is de-pressurised (downstream drain if necessary). 1) Reconstruct the valve following the exploded view on the previous page 1) Fully drain residual liquid that could be aggressive for the operator and, if possible, circulate water to internally clean the valve. 2) To easily unscrew the union nuts when dismounting, use the Easyfit multifunctional handle (supplied as an accessory) (fig. 4) or Easytorque kit...

INSTALLATION SXE-SSE valves can be installed both vertically (upward ow) or horizontally (SXE with a minimum 0.2 bar back pressure). Before proceeding with installation. please follow these instructions carefully: 1) Check that the pipes to be connected to the valve are aligned in order to avoid mechanical stress on the threaded joints. 2) Unscrew the union nuts (1) from the body (4) and insert them in the pipe segments. 3) Solvent weld or screw the end connectors (2) onto the pipe segments. 4) Position the valve body between the end connectors (g. 9). 5) Fit the union nuts on the valve...
