Petron Thermoplast offers the best and heavy-duty ball valve quality of the PVDF Dual Block 2 Way Ball Valve Series to the water and wastewater industries and also the best heavy-duty ball valve series for the agricultural industries.
We have series for PVDF ball valve called Dual Block Series. When two seating surfaces are used to lock off the pressure from both ends of a PVDF Dual Block 2 – Way Ball Valve, that valve is known as a Dual Block 2-Way Ball Valve.
For each valve, the fluid characteristics, pressure and temperature must be taken into account during the choice. The intended function of the valve, on the other hand, may be the most essential consideration. You can choose from a variety of setups depending on your process and demands and industrial water application requirements.
In operating conditions where vibration or thermal expansion may compromise performance of the standard, the PVDF Dual Block 2-Way Ball Valve technology allows the P2 Valve to shine. A patented union-nut locking device prevents back-off during harsh service conditions. The system is easy to install and does not require any special tools.
PETRONTHERMOPLAST has developed a VKD DUAL BLOCK® ball valve to introduce a high reference standard in thermosplastic valve design. VKD is a True Union ball valve that meets the most stringent needs required by industrial applications.
• Connection system for solvent weld, threaded and flanged joints
• Patented SEAT STOP® ball carrier system that lets you micro-adjust ball
seats and minimise the axial force effect
• Easy radial dismounting allowing quick replacement of O-rings and ball
seats without any need for tools
• PN16 True Union valve body made for rigid PVC-U injection moulding
equipped with built-in bores for actuation. ISO 9393 compliant test requi-
sites
• Option of dismounting downstream pipes with the valve in the closed
position
• Floating full bore ball with high surface finish
• Integrated bracket for valve anchoring
• Ball seat carriers can be adjusted using the Easytorque adjustment kit
• Possibility to have handle with integrated LSQT limit micro switch, even as
a retrofit in existing installations

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).
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.
