BuTech™ Valves
BuTech high pressure valves,
fittings and tubing are available in a variety of
materials and pressure ratings to 150,000 psi. Specific
series models utilize the same pressure connections
as our gas boosters.

Air Pilot Switches
Like a pressure switch,
these units are designed to sense pressure, but produce
an air signal up to 150 psi. |
 |
Regulating Relief and Back Pressure Control Valves
Provide over pressure on any
high pressure, low flow gas or liquid system.
|
|
Gas Receivers
Gas receivers
in 10,000 and 20,000 psi series. Eleven models from
20 to 897 cu. in. displacements.
|
|
Filters
|
|
|
These
units are designed as the final protection with
gas boosters handling purified gases, or liquid
pumps handling pre-filtered clean liquids. The elements
do not have sufficient area to be practical for
more than occasional particle migration due to pump
wear or improperly cleaned piping or containers.
They have proven to be good insurance particularly
on high-pressure gas systems. |

Stainless Steel
Check Valves
|
|
|
Combining
the best features of durability and positive sealing,
these unique valves are constructed throughout of
316 Series Stainless Steel for the high corrosion
resistance essential in the chemical, processing
and power generating industries. |
|
|
PTFE
seat seal for positive bubble-tight sealing (with
gas) from cryogenic to 3750 F (1900C) temperatures.
Seals also available for radioactive environments,
or up to 5000F steam. Can be furnished without soft
seat for higher temperature steam service.
|
|
|
Sizes
1/4" through 1” use a ball, and for reduced
inertia, the larger sizes (1-1/4”,1-1/2” and 2”)
use a poppet. Cracking pressure is 1-4psi.
|
|
|
Larger
valves can be furnished for flange mounting to customer
specifications on special quantity orders. Consult
factory. |
|
|
Semi-soft
means the check ball or poppet initially seats on
the PTFE, but after the PTFE deflects a slight amount,
the ball or poppet comes to rest against the metal
seat so the PTFE does not have to absorb the full
load of the high pressure. |
|
|
Internal
passages have flow capacity equal to or greater
than double extra heavy pipe of the same size that
would be required to carry the rated pressure (see
CV factor in chart below). |
|
|
Typical
of good Haskel design is the removal of springs
from the flow path. The larger spring is outside
the flow and simply provides a preload for the disk.
The smaller spring, inside the cage, actuats the
ball or poppet but the flow, which is routed through
the cage windows, misses the spring entirely. This
is why the valves will stand extremely high shock
loads and have been tested at rapid high shock up
to 2 million cycles without failure. |

Air Operated
Directional Control And Release
Valves
|
|
|
They
are seated poppet or ball design for virtually zero
leakage at high pressures with low viscosity fluids.
They are not “bubble-tight” on gas.
Note: Normally open models will
generally hold a tighter seal on low viscosity liquid
or gas because seating force does not depend on
inlet pressure. |
|
|
They are directly
air-actuated for ideal system compatibility in wet
or hazardous areas, or when used with air driven
pumps or boosters. Yet, if electronic or electrical
control is preferred, they can be actuated with
any of the wide selection of subminiature 3-way
solenoid air valves available from many manufacturers.
|
|
|
They
employ the same basic area ratio principle used
in Haskel pumps enabling high forces to be easily
and directly controlled from low-pressure plant
main or instrument air |
|
|
Although not
normally considered for pressure control, all of
the normally open 2-way models can do double-duty
in a circuit by also providing a safety relief function
simply by installing a small air regulator in their
pilot line (schematics next page). |
