Description
When pressure at V2 rises above the spring bias pressure, the check seat is pushed away from the piston and flow is allowed from V2 to C2. When load pressure at C2 rises above the pressure setting, flow is relieved from C2 to V2. With pilot pressure at V1–C1, the pressure setting is reduced in proportion to the stated ratio of the valve, until opening and allowing flow from C2 to V2. The spring chamber is drained to V2. The valve applies a balanced piston and relief is operated at the valve setting independent of back-pressure at V2. However, the piloted opening of the valve remains subject to additive pressure at port V2. For safety and compactness, the C2 port is gasket mounted the actuator.
Note: port identified with M are not protected with calibrated orifice but in direct connection with pressure channels.
描述
當V2處的壓力上升到高于彈簧偏置壓力時，止回閥座被推離活塞，并允許從V2到C2的流量。 當C2處的負載壓力上升到壓力設定值以上時，流量從C2釋放到V2。 在先導壓力為V1-C1的情況下，壓力設定值按閥的規(guī)定比例成比例減小，直到打開并允許從C2到V2的流量為止。 彈簧腔排空至V2。 閥門使用平衡活塞，并且在閥門設定值下操作安全閥，而與V2的背壓無關。 但是，閥的先導打開仍會受到端口V2處附加壓力的影響。 為了安全和緊湊，C2端口通過墊圈安裝在執(zhí)行機構上。
注意：標記為M的端口沒有經過校準的節(jié)流孔保護，而是與壓力通道直接連接。
