世伟洛克® 减压调压阀，圆顶加载
一般工业用（SGRD 系列）和高灵敏度（SHRD 系列）减压型圆顶加载调压阀适用于需要手动或远程操作调压阀和需要精确设定压力控制的各种工业应用。
获取工艺调压阀选型的帮助SGRD 和 SHRD 系列调压阀经过精心设计，可确保在苛刻的环境中经久耐用。其阀体由 316L 不锈钢制成，具有更强的耐腐蚀性，使用寿命更长。这些调压阀的内部密封有多种材料可供选择，从而提高了与各种化学品和不同压力条件的兼容性。
减压型圆顶加载调压阀在保持稳定出口压力方面性能卓越。这些调压阀利用压力圆顶代替设置弹簧进行控制，从而有效地减少了衰减。无论进口压力如何波动或流量如何变化，这种设计都能确保一致的出口压力。
