Split-Body Valves Carbon Steel - 760V Series | Valpres

Valpres 760V Carbon Steel Ball Valve

The Valpres 760V is a 2-piece split-body, flanged DIN ball valve with ASTM A352 LCB carbon steel body. It is used in PN16 and PN40 process lines where shut-off service is required over a temperature range from -40°C to +180°C.

Technical Characteristics

• Nominal sizes: DN15–DN200
• Pressure rating: PN40 up to DN50, or PN40 up to DN200 in 760V41 execution
• Vacuum capability: 10⁻² torr
• Ball: A351 CF8M / A479 TP304
• Stem: A479 TP304 / 17-4PH
• Seats: TFM-MPTFE
• Stem seal / body gasket: Graphoil and PTFE
• O-rings: FKM
• ISO top mounting for actuator installation

Variants and Selection Difference

• 760V01: PN40 up to DN50; PN16 from DN65 to DN200. Used where the line pressure class changes with valve size.
• 760V41: PN40 up to DN200, with trunnion-related Δp limitation of 25 bar. Selected when PN40 flange rating is required across larger sizes.

Standards and Certifications

Available executions include TÜV, SIL 3, ATEX, fire-safe according to EN ISO 10497 / API 607, and fugitive emission tested according to ISO 15848-1. Certification requirements should be confirmed against the project valve schedule and medium classification.

Typical Applications

• Industrial water and utility lines
• Compressed air and inert gas systems
• Fuel and methane service, subject to material compatibility
• Process fluids compatible with LCB, TFM-MPTFE, Graphoil and FKM
• Automated on/off isolation in process plants, HVAC energy centers and industrial skids

Actuation and Operation

The ISO top mounting allows installation of pneumatic, electric or hydraulic actuators. Actuator sizing should consider DN, pressure differential, operating temperature, cycle frequency, safety factor and fail-open or fail-close philosophy.

Sealing and Leakage Considerations

TFM-MPTFE seats are used for tight shut-off in compatible fluids. Graphoil and PTFE sealing elements support the specified temperature envelope, while FKM O-rings must be checked against chemical exposure and low-temperature operation.

Selection Criteria

The 760V is selected when a carbon steel split-body flanged ball valve is required for PN16/PN40 service with a higher temperature limit than standard PTFE-seated designs. Verify DN, PN, Kv, Δp, temperature, actuator torque, fire-safe requirement and ISO 15848 fugitive emission class.

FAQ

• Can it be automated? Yes, the ISO top mounting supports actuator installation.
• Is it suitable for gas service? Yes, if materials, pressure, temperature and certification requirements match the gas duty.
• When is 760V41 preferred? When PN40 rating is required up to DN200 and the stated Δp limitation is acceptable.
