주요 이점 및 장점
-
Specialized Liquid Service Design: Unlike standard gas regulators, the 627W and 627WH feature internal trim and materials designed to withstand the velocity and potential cavitation effects associated with liquid flow. The 627WH (High Pressure) variant is specifically reinforced for even more demanding setpoints.
-
Tight Shutoff Capability: To prevent downstream pressure creep during no-flow conditions, these regulators utilize high-quality soft-seat materials. This ensures a bubble-tight shutoff, which is critical for protecting downstream equipment and maintaining system integrity in liquid headers.
-
Stainless Steel Construction: For applications involving corrosive fluids or harsh environments, these series are available in full stainless steel constructions. This provides excellent resistance to chemical attack and atmospheric corrosion, extending the service life of the valve.
-
In-Line Maintenance: The 627W and 627WH are designed for ease of service. The trim parts, including the orifice and valve disk, can be inspected or replaced without removing the regulator body from the pipeline. This significantly reduces downtime and maintenance labor costs.
-
Rugged Construction: Built with the same legendary durability as the rest of the 627 “Big Joe” family, these regulators feature heavy-walled bodies and robust internal components. They are designed to operate reliably in the vibration-prone and high-stress environments of industrial pumping stations and oilfields.
-
Versatility in Application: With multiple body sizes and a wide range of spring options, these regulators can be tailored to meet a diverse array of liquid pressure control requirements across different industries.
