An ASTM A216 WCB Regulator is a pressure regulation device crafted from carbon steel castings conforming to ASTM A216 WCB standards. Typically employed for valves, flanges, fittings, or other pressure-containing components in high-temperature applications, these regulators utilize force balance mechanisms to maintain desired pressure levels. Comprising components such as set screws, springs, diaphragms, and plugs, they operate by balancing opposing forces to achieve precise control over fluid pressure.
