SERIES 830T THREE WAY VALVE

Transcription

1 SERIES 80T THREE WAY VALVE The series 80T three-way valve is designed for diverting service or mixing service applications. A diverting service valve takes common stream and splits it into two outlet ports. A mixing service valve combines two fluid streams and discharges the mixed fluid to a common outlet port. The 80T three-way valve actually performs the function of two opposite-acting standard two-way valves. So the use of one valve instead of two is very economical. Our various trim types and end connections of the 80T valves give you design flexibility that can surely satisfy your system requirements. The 80T valve is available in size /4" - 0" and ANSI 50 and 00 classes. Features High Capacity: Broad and streamlined fluid passage can pass larger amount of fluid than other threeway valves of the same size. Stable Operation: Port and top guiding or cage guiding makes the operation of the plug stable regardless of plug travel. Durability: Rugged structure and smooth operation guarantee a long maintenance-free service life. Flexibility: Various body and trim types provide design versatility for your needs. Specifications Valve Size: /4" to 0" Ratings: ANSI Class 50 and 00 End Connections: Flanged End, Welding End Materials: See Table on page Port Sizes: Full or reduced Flow Characteristic: Linear or Equal Percentage Seat Leakage: ANSI Class IV Flow Coefficient: See Table 4 on page 5 Dimensions: See Tables 5, 6 on pages 6, 7 Quality Assurance/Quality Control All Series 80T valves meet the ANSI B6.4 standard for "Valves - Flanged, Threaded, and Buttwelding End." This encompasses the dimensions, construction, testing and rating of all valves supplied. We also perform ANSI standard seat leakage and hydrostatic tests on every valve we build, and operability tests are run on each valve and actuator leaving our factory. Special tests are readily available to meet your specific project needs, including non-destructive testing of valve components and performance testing of actuator controls.
