H274
Performance capabilities:
● Pressure: ≦ 6MPa
● Temperature: -40~300 ℃
● Speed: ≦15m/s
Descriptions:
√ Double, multi-springs, balance design
√ Insert design of friction pair which suit for higher pressure than H273
√ Special design of face structure to keeping pressure balance
√ The design with reverse pressure capability which keeping face fit when pressure of system lower than vessel and ensure safety
√ Locking on the shaft by single or double bevel face or split type to ensure driving reliably
√ Fitted with cooling jacket in high-temperature application
Recommended applications:
√ For use in the industry of PTA, PVC, coal chemical, etc.
√ For use in various fluid, e.g. acid, aqueous solution, chemical products, corrosive medium
Piping plans:
√ API PLAN 53/54
