Mark 501/502 Series
High Flow
The Mark 501 and Mark 502 Series are used in applications that require a higher Cv (Kv) rating without using the next highest line size. The high flow Mark 501 has Cv's (Kv's) as high as 50 (43) and the super high flow Mark 502 has Cv's (Kv's) up to 70 (60). The sliding gate seats help reduce the build-up commonly associated with high flow back pressure regulators.
Jordan’s unique self-operated sliding gate back pressure regulator features the sliding gate seat:
- Shorter stroke than a globe or plug-style valve: faster response, smaller and lighter weight than a globe-style regulator, less build-up
- Straight through flow: less turbulence, erosion or noise, improved rangeability, longer seat life
- Ease of maintenance: interchangeable seats and Cv’s, fewer spare parts, self-cleaning seats, no gaskets or o-rings
