V-Port discs to ensure optimum controllability and flow.
- All internal surfaces are accurately
machined to provide maximum performance.
- Renewable seat rings made from hardened
stainless steel and faced with Stellite.
- The disc is hardened, ground and lapped
for accurate, leak free sealing.
- Standard material is carbon steel body
(ASME SA105) with 13% chrome stainless steel trim.

The Hancock Flow Control Valve is a
combination valve and flow control instrument equipped with a
special micrometer dial and pointer which enable the operator to
set the valve opening to within one hundredth of a turn of the
handwheel. Any desired setting can be instantly duplicated. Each
valve is fitted with a scientifically designed V-Port valve disc
ensuring proportional flow throughout the entire lift of the
stem. It is a hand-operated valve with a straight line flow
characteristics. A separate shut-off seating surface, removed
from the controlling V-Ports, eliminates the necessity of using
a second valve for shut off purposes. |
