CPVC DUAL BLOCK 3-WAY BALL VALVE

What is CPVC Dual Block 3-Way Ball Valve?

In most cases, the CPVC Dual Block 3-Way Ball Valve has two modes of operation: input and output. A three-way ball valve may be recommended in some systems when more than one medium is used. Instead of just two ports (entries), 3-way ball valves have three.

This multiport arrangement can divert fluid from the primary valve input in two different directions (instead of just one) via two independent valve outputs. The primary flow line is served by two separate and alternate inlets, which is another common application of CPVC Dual Block 3-Way Ball Valves.

Flow pattern, handle direction, and the range of 90-degree spin that the handle can make are all used to classify cpvc three-way ball valves. Because of how the valve ball is drilled and the pipe design, gas and liquid flow can be diverted, mixed, blocked, or completely stopped in one direction. By reducing the need for an additional tee and valve, multiport valves save space.

PETRONTHERMOPLAST has developed a TKD DUAL BLOCK® ball valve to introduce a high reference standard in thermosplastic valve design. TKD is a
True Union diverting and mixing ball valve that meets the most stringent needs required in 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 axial force effects
• 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
• High surface finish stem with double O-Ring and double connection key
to the ball, equipped with visual ball position indicator for correct handle
installation
• Integrated bracket for valve anchoring
• Possibility of installing pneumatic and/or electric actuators thanks to the
robust anchor tower for easy and quick automation using the Power Quick
module (optional)
• Possibility to have handle with integrated LSQT limit micro switch, even as
a retrofit in existing installations

CPVC DUAL BLOCK 3-WAY BALL VALVE INFORMATION

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).

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.
