PVDF CHECK VALVE
Petron Thermoplast To make Polyvinylidene fluoride made valves, The PVDF Union Ball Valve and Spring Check Valve is mounted and ground to a precise tolerance. This reduces torque requirements and makes handling easier.
Spring Check Valves are designed to be completely closed. A wide range of water treatment and chlorination applications benefit from the use of these PVDF True Union Check Valves.

The Easyfit check valve line developed with Giugiaro Design offers two different versions: SXE with ball shutter and SSE with spring loaded shutter. Easyfit check valves stand out for the innovative installation method that guarantees reliable service over time. This valve is also equipped with the customisable Labelling System.
• Connection system for solvent weld and threaded joints
• Valve material compatibility PVDF with water conveyance, drinking water and other food substances according to current regulations
• PN16 True Union valve body made for PVDF injection moulding and European Directive 2014/68/EU (PED) compliant for pressurised equipment.
ISO 9393 compliant test requirements
• Fully interchangeable with VXE and VEE DN 10÷50 ball valve models
• Union nuts with rack for tightening adjustment via Easyfit handle or via Easytorque adjustment kit (available as accessories)
• Vertical (preferable for SXE model) and horizontal installation potential

PVDF CHECK VALVE
PRESSURE VARIATION ACCORDING TO TEMPERATURE
For water and harmless fluids to which the material is classified as CHEMICALLY RESISTANT. In other cases, a reduction of the nominal PN pressure is required (25 years
with safety factor).
PRESSURE DROP GRAPH
KV 100 FLOW COEFFICIENT
The Kv 100 flow coefficient is the Q flow rate of litres per minute of water at a temperature of 20°C that will generate Δp= 1 bar pressure drop at a certain valve position. The Kv100 values shown in the table are calculated with the valve completely open.
