Detailed introduction

Forged steel fixed ball valve is a type of valve widely used in industrial fields, especially suitable for chemical, metallurgical, petroleum, pharmaceutical and other industries of high pressure medium pipeline. The design of this valve can meet the needs of different working temperatures and media, and has good sealing performance and corrosion resistance.

Design feature

Forged steel fixed ball valve usually has two design forms: two-piece structure and three-piece structure. The two-piece structure is connected through the central thread and sealed with PTFE gaskets; The three-piece structure is connected by bolts. Depending on the selected seat and gasket/packing material, it can be adapted to different working conditions. In addition, the valve also has full/reduced diameter, 90 degree positioning and locking structure, special form of “Y” head handle, fire and anti-static design, a pair of opposite butterfly springs, anti-blowout stem, stem center double seal structure and bolt, threaded gasket seal valve cover design features.

Installation and application

The installation of forged steel fixed ball valves needs to ensure that the internal structure type conforms to the flow direction of the medium, and the installation posture should meet the specific requirements and operating requirements of the valve structure type. The correct installation posture can not only ensure the normal operation of the valve, but also reflect the combination of technology and artistry in modern art modeling.

Scope of application

The forged steel fixed ball valve is suitable for a variety of high pressure medium transmission pipelines, the applicable temperature range is -196 ~ 450℃, the driving mode includes manual, pneumatic, electric, hydraulic, turbine and so on. Nominal diameters from 1/2″ to 12″, nominal pressures from 150LB to 1500LB. Applicable media include water, gas, oil, natural gas and acid and alkali corrosive media.
