Page: 8 / 45

Due to the use of high-quality stainless steel and seal
materials complying with the specified requirements, the
double seat ball valve DELTA DKR2 is applicable in the food
and beverage industries as well as in the chemical and
pharmaceutical industries.
The field of application of the DELTA DKR2 valve comprises the
separation of two line sections with different fluids (B and C)
by two independent seals with intermediate leakage chamber and
free drain (D) to the atmosphere.
Actuation of the pneumatic turning actuator with air connection
at (A), reset into the limit position "closed" by spring force.
- The free opening cross section has the same dimension as the
nominal diameter of the pipeline.
- Smooth valve passage without diversion of the fluid.
- Cleaning of the leakage chamber by supply of cleaning liquids via
the cleaning connection (E).
- During the operating process, operating leakages bleed from the
leakage drain (D) downwards. If a cleaning line is not connected,
the cleaning connection (E) must be sealed by a plug or operating
leakages must be discharged.
- The cleaning connection (E) can be used to vent the leakage
chamber for a faster emptying or to sterilize the leakage chamber
with steam.
