??MRQA型阀是一种具有自动卸荷功能的溢流式安全阀。当系统压力达到设定值时,该阀可使油泵自动卸荷。当系统压力下降到设定值的68%或78%时,泵重新开始工作。为保证以上工作,必须使用蓄能器(见液压原理图)以保证系统压力。集成在阀板中或者叠加在MRQA/C型阀中的单向阀,可以阻止蓄能器在阀打开时卸荷。该系统可保持系统压力,避免油液发热,并减小能耗。在不减小连接尺寸的情况下,建议蓄能器尽可能的靠近MRQA阀安装。— 工作周期取决于泵的流量、蓄能器容量和预充压力,以及系统工作需要的流量。MRQA-3/1/M/C/42V MRQA-5/1/M/C/42V MRQA-6/1/M/C/42V MRQA-3/2/M/C/42VMRQA-5/2/M/C/42V MRQA-6/2/M/C/42V CR2-22N-K CR3-22N-K CR4-22N-K CR5-22N-K CR6-22N-K CR2-22V-K CR3-22V-K CR4-22V-K CR5-22V-K CR6-22V-K CRQ3-M1-12V CRQ4-M1-12V CRQ5-M1-12V CRQ6-M1-12V CRQ3/12 CRQ4/12 CRQ5/12 CRQ6/12 CD1-W3/M1/10V CD1-W3/10 CD1-W4/10 CD1-W5/10 CD1-W6/10 RM2-W3/31N/K RM2-W4/31N/K RM2-W5/31N/K RM2-W6/31N/KRM3-W3/30N/M1 RM3-W4/30N/M1 RM3-W5/30N/M1 RM3-W6/30N/M1RQ5-W3M/41V RQ5-W5M/41V RQ5-W6M/41V RQ7-W3M/41V RQ7-W5M/41V RQ7-W6M/41V RQM5-W3AM/60N-K1/CM RQM5-W3/A/51-A230 RQM5-W5/A/51-D24 RQM5-W6/D/51-A230 RQM5-W3/B/51-A230 RQM7-W3A-60N-D12-K1CM RQ3-P3/41 RQ3-P5/41 PQ3-P6/41 RQ5-P3/41 RQ5-P5/41 RQ5-P6/41RQ7-P3/41 RQ7-P5/41 RQ7-P6/41RQM(电磁式)RQM3-P5/A/60N-A230K1 RQM3-P5/A/60N-A110K1 RQM3-P5/A/60N-D24K1RQM3-P5/M/60N-A230K1 RQM3-P5/M/60N-D24K1 RQM3-P6/A/60N-A230K1RQM3-P6/A/60N-A110K1 RQM3-P6/A/60N-D24K1 RQM3-P6/M/60N-A230K1RQM3-P6/M/60N-D24K1 RQM5-P6/A/60N-A230K1 RQM5-P6/A/60N-A110K1RQM5-P6/A/60N-D24K1 RQM5-P6/M/60N-A230K1 RQM5-P6/M/60N-D24K1RQM5-P5/A/60N-A230K1 RQM5-P5/A/60N-A110K1 RQM5-P5/A/60N-D24K1RQM5-P5/M/60N-A230K1 RQM5-P5/M/60N-D24K1 RQM7-P5/A/60N-A230K1RQM7-P5/A/60N-A110K1 RQM7-P5/A/60N-D24K1 RQM7-P5/M/60N-A230K1RQM7-P5/M/60N-D24K1 RQM7-P6/A/60N-A230K1 RQM7-P6/A/60N-A110K1RQM7-P6/A/60N-D24K1 RQM7-P6/M/60N-A230K1 RQM7-P6/M/60N-D24K1RQM3-P5/A/60N-A230K1 RQM3-P5/A/60N-A110K1 RQM3-P5/A/60N-D24K1RQM3-P5/M/60N-A230K1 RQM3-P5/M/60N-D24K1 RQM3-P6/A/60N-A230K1RQM3-P6/A/60N-A110K1 RQM3-P6/A/60N-D24K1 RQM3-P6/M/60N-A230K1RQM3-P6/M/60N-D24K1 RQM5-P6/A/60N-A230K1 RQM5-P6/A/60N-A110K1RQM5-P6/A/60N-D24K1 RQM5-P6/M/60N-A230K1 RQM5-P6/M/60N-D24K1RQM5-P5/A/60N-A230K1 RQM5-P5/A/60N-A110K1 RQM5-P5/A/60N-D24K1RQM5-P5/M/60N-A230K1 RQM5-P5/M/60N-D24K1 RQM7-P5/A/60N-A230K1RQM7-P5/A/60N-A110K1 RQM7-P5/A/60N-D24K1 RQM7-P5/M/60N-A230K1RQM7-P5/M/60N-D24K1 RQM7-P6/A/60N-A230K1 RQM7-P6/A/60N-A110K1RQM7-P6/A/60N-D24K1 RQM7-P6/M/60N-A230K1 RQM7-P6/M/60N-D24K1 压力补偿器 PCDK6 PCK06-PV/11N PCK06-P4/11N PCK06-P8/11N PCK06-PTV/11N PCK06-PT4/11N PCK06-PT8/11N RQR3-P3/1/I/M/42VRQ3-P3/41RQ3-P5/41PQ3-P6/41RQ5-P3/41RQ5-P5/41RQ5-P6/41RQ7-P3/41RQ7-P5/41RQ7-P6/41RQA-3PRQR3-P3/2/40意大利RQA5-P3/2/40RQA7-P3/2/40RQM3-P5/A/60N-A230K1RQM3-P5/A/60N-A110K1RQM3-P5/A/60N-D24K1RQM3-P5/M/60N-A230K1RQM3-P5/M/60N-D24K1RQM3-P6/A/60N-A230K1RQM3-P6/A/60N-A110K1RQM3-P6/A/60N-D24K1RQM3-P6/M/60N-A230K1RQM3-P6/M/60N-D24K1RQM5-P6/A/60N-A230K1RQM5-P6/A/60N-A110K1RQM5-P6/A/60N-D24K1RQM5-P6/M/60N-A230K1RQM5-P6/M/60N-D24K1RQM5-P5/A/60N-A230K1RQM5-P5/A/60N-A110K1RQM5-P5/A/60N-D24K1RQM5-P5/M/60N-A230K1RQM5-P5/M/60N-D24K1RQM7-P5/A/60N-A230K1RQM7-P5/A/60N-A110K1RQM7-P5/A/60N-D24K1RQM7-P5/M/60N-A230K1RQM7-P5/M/60N-D24K1RQM7-P6/A/60N-A230K1RQM7-P6/A/60N-A110K1RQM7-P6/A/60N-D24K1RQM7-P6/M/60N-A230K1RQM7-P6/M/60N-D24K1Z3P5R/C/22V Z5P5R/C/22V S3-P3/C/20V S3-P4/C/20V S3-P5/C/20V S3-P6/C/20V S5-P3/C/20V S5-P4/C/20V S5-P5/C/20V S5-P6/C/20V U3-P3/C/20V U3-P4/C/20V U3-P5/C/20V U3-P6/C/20V T3-P3/C/20V T3-P4/C/20V T3-P5/C/20V T3-P6/C/20V X3-P3/C/20V X3-P4/C/20V X3-P5/C/20V X3-P6/C/20V U5-P3/C/20V U5-P4/C/20V U5-P5/C/20V U5-P6/C/20V DZC5-070/10N-II/K1 DZC5-070/10N-EE/K1 DZC5-140/10N-EE/K1 DZC5-140/10N-EE/K1 DZC5-210/10NIE/K1 DZC7-210/10NIE/K1 DDC2-10-J-20-22 DZC7-210/10NIE/K1DZC7-140/10V/II/K11 DZC7-210/10V/II/K11 DZC8-070/10V/II/K11 DZC8-070/10N-EE/K1T5-P3/C/20V T5-P4/C/20V T5-P5/C/20V T5-P6/C/20V 平衡阀ZC2-P3/M1/51 ZC2-P4/M1/51 ZC2-P5/M1/51 ZC07-P3/51 ZC07-P4/51 ZC07-P5/51 ZC4-P3/51 ZC4-P4/51 ZC4-P5/51 ZC5-P3/51 ZC5-P4/51 ZC5-P5/51X5-P3/C/20V X5-P4/C/20V X5-P5/C/20V X5-P6/C/20V RQR5-P3/2/40
