Description
THE BV10-40 IS A SPOOL TYPE PRESSURE TO SHIFT, SPRING RETURN, THREE POSITION VALVE. IT IS DESIGNED SO THAT OIL PRESSURE AT EITHER INLET PORT 1 OR 4 CAN BE DIRECTED TO PORT 2.
Operation
THE BV10-40 IS NORMALLY USED TO RELEASE A SPRING APPLIED PARK BRAKE WHENEVER HYDRAULIC POWER IS DIRECTED TO MOVE A LOAD. WHEN THE PRESSURE DIFFERENTIAL BETWEEN PORTS 1 AND 4 EXCEEDS APPROXIMATELY 80 psi, THE SPOOL HAS MOVED FAR ENOUGH TO CLOSE THE TANK PORT 3 AND OPEN THE PORT THAT HAS THE HIGHER PRESSURE BETWEEN PORT 1 AND PORT 4 TO PORT 2.
