 | Simple Operation: Spread the
line with operating bolts using only a bar or pipe. Rotate spectacle
plate and tighten again in seconds, without special tools (See
A). |
| Compact Design: Unique bolt
head design allows installation and operation in limited space. |
| Positive position indication:
Visible portion of spectacle plate clearly indicates if valve is
open or closed. |
| Packing Variation: Wide range
of packings are available to suit service requirements including
spiral wound stainless steel for high temperatures. Body packing (See
B) is standard but spectacle plate packing is optional. |
| Full Flow: Minimal
turbulence occurs through full round port and pressure drop is
negligible. |
| Minimum maintenance: High
quality alloy nuts and bolts have through bolt-to-nut lubrication
feature (See D). Spectacle plate
is plated for corrosion resistance on carbon steel blinds. |
| End Connections: Available
with but weld or flanged ends with optional B16.10 end-to-end
dimensions. |
| Time saving: Operate only a
few bolts, instead of loosening and tightening 4 to 12 bolts on a
standard flange. Reversing the plate usually takes less than a
minute. |
| Safety: Absolute
assurance of no downstream leakage. Alignment-locking
pin is standard. |
