應用與選型指引
Choose this execution where a water system needs upstream pressure protection at waterworks ratings: downstream of pumps and supply headers that must not rise above a set pressure, on branch take-offs that need a sustaining function holding a minimum upstream level while the valve spills the surplus, and on fire-service or irrigation headers where a pilot-set relief point matters more than continuous throttling. Confirm the size within the tabulated DN range against the PN1.0/PN1.6/PN2.5 flange drilling, orient the valve on horizontal piping as the source specifies, and set the pilot to the required relief or sustaining pressure at commissioning.
常見問題
What does the 500X do differently from a spring relief valve?
A spring relief snaps open and re-closes, cycling with every pressure ripple. The 500X is a pilot-controlled, diaphragm-actuated valve: the pilot modulates the main valve so it relieves or sustains at the set point with controlled travel, which suits pump headers and supply mains where smooth upstream-pressure protection matters more than a crack-open action.
What sizes and ratings does this execution cover?
The source page tabulates main dimensions from DN20 to DN800, with flange dimensions D, D1, D2 and bolt circles given separately for PN1.0, PN1.6 and PN2.5. Face-to-face L, overall A/A1 and heights H/H1 are tabulated per size, and the valve is installed on horizontal piping.
What information is needed to quote a 500X pressure relief valve?
Nominal size within the tabulated range, the flange pressure class (PN1.0, PN1.6 or PN2.5) against the system, the required relief or sustaining set pressure for the pilot, and the installation orientation - the source specifies horizontal piping. The pilot setting fixes the protection point; the size and class fix the flange pattern.

報價
可直接報價的詢問應說明：公稱口徑與壓力額定、閥體與閥座材質偏好、端部連接、操作方式，以及含溫度的使用介質。本頁的典型值為基準參考範圍；具有約束力的數值於報價時確認。

供應條件、訂購數量與交期按訂單議定——請在詢問時說明目的地國家與所需時程。
儲存與運輸
閥門儲存時應保護閥座與密封件免受紫外線、臭氧與變形影響，安裝前保留端面保護蓋；彈性體或 PTFE 閥座結構應避免長期戶外存放——閥座材料在陽光直射與冰凍條件下老化最快。
