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 and SHRD series regulators are engineered for durability in demanding environments. Their bodies are constructed from 316L stainless steel, enhancing corrosion resistance and longevity. These regulators feature internal seals available in various materials, providing improved compatibility with a wide range of chemicals and pressure conditions.
Pressure-reducing, dome-loaded regulators offer superior performance in maintaining stable outlet pressures. By utilizing a pressure dome instead of a set spring for control, these regulators effectively minimize droop. This design ensures consistent outlet pressures, regardless of fluctuations in inlet pressure or flow variations.
