STANDARD AND HOLLOW TYPES

ZRD & ZRDH Series - Capacity: 10 to 500 tons
Max. Operating: 10,000 psi - Stroke: 6" to 20.13"
Features
1. The double acting is designed to produce greater speed
and positive control for applications requiring an extra
measure of strength, quality, reliability and safety.
2. Interfaces with automated operations while providing
both powered push and pull cycles.
3. All models come with 3/8" NPT fast-flow quick-
