DESCRIPTION
Upstream Vacuum, Jorlon Diaphragm
The Mark 55 Series control very accurately and shutoff tightly to maintain the proper vacuum setting. They are used to maintain vacuums at predetermined settings and to regulate vacuums on evaporators, cookers, grinding fixtures, milking machines, altitude chambers and other vacuum systems.
Features & Benefits
- Sliding gate seats provide:
– Straight-through flow for reduced turbulence and quiet operation
– Short stroke for fast response and accurate regulation
– Easily interchangeable Cv’s
– Tight shutoff - All metal-to-metal contacts – no gaskets, o-rings, or elastomer parts to wear out
- Compact design and simple construction – allows fast, simple installation and easy maintenance
- Sliding Gate Trim — Unique seat design provides unsurpassed trim life and accuracy
- Fast Response — The short stroke of the sliding gate means fast response to changes in process conditions, resulting in less offset in pressure
- Straight-Through Flow — The flow is straight through the valve seats and body. Direction of the disc travel is at right angles with the flow, not opposed to the direction of the flow. Thus the flow does not unbalance the seats
- Quiet Operation — The design of the Sliding Gate seats make them quieter than other types of regulators. The disc and plate are always in contact, which eliminates chattering. Straight-through flow minimizes turbulence
- Minimum Maintenance — The Mark 50 sliding gate seats require no special tools for disassembly. The seats are pre-lapped at the factory and are self-lapping while in operation ensuring a continual tight shutoff
