Advanced aftermarket services for valve users
Tyco Valves and Controls now offers customers the benefit of guaranteed performance with an advanced aftermarket service, including dedicated valve repair for power plant installations.
The series 5100 valve is the latest design innovation in pilot-operated pressure relief valve technology from Tyco Flow Control and its Anderson Greenwood brand to meet the most demanding applications.
It is the first nonflowing modulating pilot-operated pressure relief valve that is certified under the stringent requirements of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section I with steam service capacity certifications in accordance with Section I and water service capacity certifications.
Additionally, it is the first all-plastic soft seat and sealed valve that operates as a nonflowing modulating pilot, requiring no component changes to handle alternating steam and water conditions.
This design opens in proportion to relief demand and is suitable for hot water, flashing water and steam service without the operational performance problems usually found with spring-loaded pressure relief valves on economiser service.
The valve features soft seats for premium tightness before and after relief cycles.
The design offers a great alternative to traditional metal seated valves used in these installations.
Because of total valve tightness to at least 96% of set pressure, the system can be operated closer to set pressure without valve leakage.
The result is greater system production capability.
Resilient seats greatly extend service life.
Costly and time-consuming metal seat lapping is unnecessary.
It also requires no elastomer seats or seals.
The result is a modulating, soft-seated, pilot operated valve offering premium tightness with the ability to handle temperatures from -54C to +268C and a set pressure range of 1 to 425 bar.
