PPH BUTTERFLY VALVE MANUFACTURER

What is PPH Butterfly Valve?

PPH Butterfly Valve Manufacturer company in India. It is a quarter-turn rotational motion valve for stopping, regulating, and starting flow. A disc is placed on a revolving shaft in a butterfly valve.

The disc stops the line when the butterfly valve is fully closed. The disc of the PP butterfly valve is at a right angle to the flow of gas or liquid when it is completely opened.

The valve may be completely closed or opened by rotating the handle 90 degrees. Large PPH Butterfly Valves are frequently fitted with a gearbox, which connects the hand wheel to the stem through gears. This makes the valve’s functioning easier, but it comes at the price of speed.

The Butterfly Valves are popular because of their dependability and low maintenance needs. Because of the reduced wear, the BVF Valves are very useful life can be extended. This lowers direct operating expenses and minimises the number of hours spent on valve maintenance.

BUTTERFLY VALVE

PRESSURE VARIATION ACCORDING TO TEMPERATURE

For water and non-hazardous fluids with regard to which the material is classified as CHEMICALLY RESIS- TANT. In other cases, a reduction of the nominal pressure PN 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.

RELATIVE FLOW COEFFICIENT GRAPH

The relative flow coefficient is the flow rate through the valve as a function of the degree of valve opening. Horizontal axis: Percentage opening
