Technical Data | Valve Body Pressure Rating For Carbon Steel, Stainless Steel, Alloy 20 Valves: ANSI Class 600 1/4" - 2" —Carbon Steel 1480 psi 1/4" - 2" —Stainless Steel 1440 psi 1/4" - 2" —Alloy 20 1200 psi Valve Body Pressure Rating for Brass Valves: 1/4" - 1" —1500 psi 1 1/4" - 2" —1000 psi This is the body pressure rating. Seat selection may lower the valve pressure rating. Example: A 3/4" Series 44 brass valve has a rating of 1500 psi at 70°F . Selection of TFE seats, operating at a fluid temperature of 160°F, limits total allowable pressure in the valve to 800 psi. Design Specifications: ANSI B16.34 ANSI B16.25 - Butt weld ends (weld end preparation) ANSI B16.11 ANSI B1.20.1 - NPT pipe threads MSS SP-25 - Valve marking MSS SP-72 - Socket weld ball valves NACE - MRO I-75 1984 Rev. Category 3 Seals and Thrust Bearings: PEEK, Graphite and Polyfill Temperature Range: Dependent upon seal and seat choice, will operate from -50°F to +600°F. Pressure Range: Valves will operate from 1 micron absolute to +1480 psi. Seat/Seal Leakage: Standard valves, less than 1 x 10-6 cc He/sec in board and through (bubble-tight is 1 x 10-4 cc He/sec). With preparation, leakage will be less than 2 x 10-9 cc He/sec. All valves100% tested to bubble-tight standards. Optional External Valve Trim: 300 Series stainless steel external components are available as an option on brass and carbon steel valves. They are standard on stainless steel and Alloy 20 valves. S-7: Complete Stainless Steel trim: handle, handle nut, lock washer, retaining nut, belleville washers, body bolts, nuts, stop pin |

Top Mounted Actuator Design | Before the actuator can be sized for any given valve application, the operating torque required for the valve must be determined. The operating torque of the ball valve is influenced by a number of factors - some are design and materials-related, others are application - (service conditions) related. Design-related factors include the type and material of the valve seats, while application factors include system pressure, media and frequency of operation.
For complete valve operating torque data, refer to Worcester’s Actuator Sizing Manual (ASM). This eight-page publication explains the concept of valve torque, presents torque curves for each seat material, and provides correction factors for media and the type of service such as on-off operation, cycle frequency, etc. |
