Stop
valve is usually used for or connecting the medium flow and is not recommended
for throttling.
The
maximum permissible leakage of the Stop Valve with non-metal elastic seals is
zero, and that of the stop valve with meal seals is 0.1xDNmm3/s. Therefore,
acceptable stop valves with metal seals possibly have slight leakage. Hence, in
the applications where there must not be any leakage,especially at the pipeline ends,stop valves with soft seals should be
used,and shutoff
valves with metal seals should not be used.
Nominal
Pressure of Brass Stop Valve is 1.6MPa. Medium temperature for metal seal is
-20℃~150℃, and medium temperature for non-metal
elastic seal is -20℃~120℃. When the stop valve is used for
saturated steam, the pressure of the saturated steam should be ≤0.6MPa.

K series: Pneumatic ball vibrator
GT series: Pneumatic turbine vibrator
R series: Pneumatic roller vibrator
SK series: Impact air hammer
Feature:
Maximum temperature 140° C _280° F
Noise level range 75 to 100 Dba
These compact pneumatic vibrators are simple in design and yet capable of deliverieng very high centrifugal forces.
The body is machined from an extruded aluminium section, inside of which a precision steel roller rotates, it is retained by two special high impact plastic end plates. For easy mounting, the body has four holes, two horizontal and two vertical.
Air is introduced through one of two inlet ports drilled at right angles to each other in the body. These inlet ports are tapped with a standard pipe thread and a pipe plug is provided for sealing the one not used. The air is exhausted through the special high impact plastic end plates whose design incorporates an air silencer.
Application:
Series R high frequency pneumatic roller vibrators provide a new approach in the movement of fine materials. Being pneumatically powered, the frequency can be controlled by the regulation of air pressure.
Examples of their uses inculde:
- Emptying hoppers
- Agitation of small particles
- Moving of fine powders
- Compaction of plastic and concrete in moulds
