Inditech Valves Pvt. Ltd. specializes in blowdown valves (BDVs) used for removing contaminated water from boilers, helping to control dissolved solids and maintain operational efficiency. They offer two types of BDVs: Continuous Blowdown (CBD) for ongoing operation at the water level, and Intermittent Blowdown (IBD) for periodic operation at the bottom. Inditech's BDVs feature unique designs to enhance performance, durability, and leak tightness across various industrial applications.

2. What is Blowdown Valve (BDV)?
• It is used in the process of
removal of a certain quantity of
contaminated water from the
boiler.
• The function of a blowdown valve
is to control the concentrations of
suspended & total dissolved
solids (TDS) in the boiler.

3. • Blowdown valves play a crucial role in the operation and
maintenance of various industrial systems, particularly in
steam boilers.
• These valves are designed to release or "blow down" water
and impurities from the boiler to maintain optimal operating
conditions and ensure the safety and efficiency of the
system.
• The function of a blowdown valve is to control the
concentrations of suspended & total dissolved solids (TDS)
in the boiler.

Blowdown Valves

4. Types of BDV
Continuous Blowdown
(CBD) Valve
Intermittent Blowdown
(IBD) Valve
• CBD is mounted at the water
level of boiler drum. Hence it is
called SURFACE BLOWDOWN.
• IBD is mounted at the bottom
of boiler drum. Hence it is
called BOTTOM BLOWDOWN
• It is SINGLE step trim.
• It is MULTIPLE step trim.
• It is in continuous operation
hence inching duty is preferred
• IBD is operated after intervals
of time hence ON-OFF duty is
preferred

5. USPs of IndiTech BDVs
• IndiTech Continuous Blowdown Valve (CBD) is an angle type valve with
a needle shaped trim in a venturi diffuser. The venturi diffuser provides
sufficient area for the high velocity flashing water, thereby avoiding
choked flow.
• IndiTech Intermittent Blowdown Valve (IBD) carries out both these
functions in sequence i.e. blowdown in open position and sealing in
closed position. This is achieved by providing a multi-step throttling
plug, which splits the total pressure drop across each step. The sealing
area is separate from the throttling area, which reduces erosion and
provides leak tightness even after prolonged usage.
