1. Low pressure drop.
2. Can be controlled by wet type electro magnetically, and piloted moving by oil pressure.
3. Can be simple and easy change the types of piloting and draining.
4. Designed by slippery spool, that can be operated under the condition of high press and large flow.
5. Only need general purpose tool to install maintenance.
6. Antirust by the phosphate on the surface, and the body appearance of the valve is black.
7. The spool size of body interior used, 06 type:Φ32mm, 04 type:Φ25mm.
1. Max. flow 1/min: 500*. 2. Max. operating: 315 kgf/cm2. 3. Max. PILDT: 250 kgf/cm2. 4. Min PILDT: 8. 5. Max. T-line backpressure: (1) Ext. drain: 210. (2) Int. drain: 140. 6. Max. change over frequency cycles/min: (1) AC: 120. (2) DC: 120. (3) R: 120. 7. Weight: 12.5kg. * The through flow is depended on the spool type.
