Product catalog summary

Product Overview

The document details the specifications and features of the Thor Split Body Stainless Steel Ball Valves, compliant with ANSI 900-1500 pressure classes. These valves are designed for use with air, water, gas, petroleum, petrochemical, and aggressive fluids.

Standard Features

Floating ball with full bore design.
Soft-seat seal made of DEVLON.
Standard flange connections per ASME B16.5.
Operating temperature and pressure as per provided diagrams.
Pressure class ANSI 900-1500.
Antistatic device compliant with EN12662-2.
Stem seal using TFM 1600 V-pack and additional FKM O-ring.
Anti blow-out stem design.
Actuator connection per ISO 5211 standard.
Closing angle greater than 7°.

Special Features (On Request)

Alternative flange types.
Sealing materials such as PTFE reinforced with glass or carbon-graphite.
PTFE cavity filled seat.
Mono-directional version with pressure-compensating hole.
Stainless steel lever, stem nuts, and springs.
Special materials for body, ball, and stem.

Certifications and Compliance

European Directive 97/23 EC (PED).
ATEX Directive 94/9/CE for explosive environments.
TA-LUFT VDI 2440 for fugitive emissions.
Fire Safe certification EN ISO 10497 / API 607.
API 6D certificate number 6D-1007.
Engineering standards: API 6D, ASME B16.34, ASME VIII div.1, EN 12516.

Features and Benefits

Antistatic device ensures electrical continuity to prevent sparks in explosive environments.
Double antifriction washer reduces break-away torque and wear.
Triple "V" seal pack plus O-ring ensures tightness after many cycles.
Spring washer maintains seal integrity despite wear and temperature changes.
Stretch graphite seal guarantees external tightness regardless of thermal excursions.
Precision machining ensures better axis alignment, longer valve life, and easier maintenance.
Carbon steel valves use certified NACE materials for corrosion resistance and ductility.
100% in-house manufacturing for quality control and flexibility.
Fire safe and ATEX certified for safety in hazardous environments.
Full traceability of manufacturing and product.

Break Away Torque Data

Break away torque values (Nm) for DEVLON seats with water at various pressures and sizes (DN15, DN20, DN25) are provided, ranging from 15 Nm at 0 bar to 60 Nm at 250 bar. Torque may vary with fluid type, temperature, and lubrication; a safety factor of 1.4 is recommended. Torque decreases with high-frequency operation. Pneumatic actuator sizing assumes minimum supply pressure of 5.6 barg.

Dimensions and Materials

Detailed dimensional tables for DN15, DN20, and DN25 valves under ANSI 900/1500 standards are included, specifying measurements such as length, diameter, and flange details.

Materials table lists components and their corresponding materials for three stainless steel grades: F304, F316, and F51 Duplex. Components include body, connector, ball, stem, seats, seals, bolts, nuts, springs, and levers. Special notes indicate availability and material substitutions on request.

Shaft Extension

Welded spindle extension with lever is described, including materials such as AISI 304 stainless steel for extension, AISI 430F for pins, DELRIN bushings, and NBR O-rings. Dimensions vary based on valve connection and drive type.

Drives and Actuators

The document provides item codes and specifications for various drive options compatible with the valves:

Bare shaft and lever operated valves in F304, F316, and F51 stainless steel for DN15, DN20, and DN25 sizes.
Double acting pneumatic actuators with connecting kits, including dimensions and weights.
Spring return pneumatic actuators with connecting kits, including dimensions and weights.
Electric actuators with connecting kits, including dimensions and weights.

Each actuator type is available in the three stainless steel grades, with specific item codes for ordering.

Critical Information and Recommendations

Torque values must consider fluid type, temperature, and lubrication; apply safety factor 1.4.
For special flange types, sealing materials, or body materials, contact sales department.
Maintenance is simplified by design, allowing on-site servicing and reducing costs.
Compliance with multiple safety and quality standards ensures suitability for oil, gas, and petrochemical applications.
