The 3-Way 4-Way Ball Valve Screwed End

Valve stem packing: 1/2 "-4" valves all use dynamic load valve stem packing devices to ensure reliable valve stem packing. By using Belleville washers, the valve stem packing can be automatically adjusted to compensate for temperature changes and normal wear. The 6 "-12" valve uses an independent packing box cover, which can be easily adjusted during valve use. The 1/2 "-2" valve also provides main stem packing and secondary stem packing. The main seal is composed of push washers and O-ring components. The adjustable valve stem packing forms a secondary seal between the valve stem and the valve body in the upper shaft neck area of the valve stem.

Four seat design: As standard, GKV-144 series valves are also equipped with an additional fourth seat. This valve seat is independently sealed to prevent leakage in the cavity area and maintain correct alignment of the sphere. The added valve seat integrates bidirectional control and closing functions into the same valve, with OFF positions located in both T-shaped and L-shaped port spheres. The GKV-144 series ball valve seat design ensures bi-directional bubble level sealing and low working torque.

Seat selection: Provides a range of seat materials to meet the needs of most

applications. TFM is a standard material for valve seats. Other options include

RPTFE, PTFE, UHMWPE, and Tek Fi ® (Carbon/graphite filled TFM). Tek-Fil ®

The valve seat provides less torque in high temperature, high cycle, and steam

applications.

Interchangeability: Many components, including ball, stem, seat, stem, and

valve body seals, can be interchanged between different models of valves of

the same size.

Unique design of GKV144 three-way and four-way ball valves

The integral casting of the upper flange ensures the correct installation

of the actuator. Under full load pressure conditions, the actuator device

can be easily and safely disassembled. The installation flange is designed

according to ISO 5211 standard and can be directly embedded for installation.

By changing the position of the travel limit pin bolt on the installation flange,

standard valves can achieve all flow modes.
