Product Introduction

The valve body of the three-way ball valve and the four-way ball valve is cast by high-quality materials and reasonable casting process. It is also forged, the ball is side-mounted, and the middle flange and neck are bolted. The three-way ball valve produced by the company mainly has L-shaped and T-shaped valve body structures, which are suitable for general industrial pipelines and long-line pipelines, and are suitable for various corrosive and non-corrosive media. The user can select the full-diameter or reduced-diameter structure according to the needs. The full-diameter valve flow diameter is consistent with the inner diameter of the pipeline to facilitate pipeline cleaning. According to the customer's requirements, the end connection can be provided as a flange connection and a butt-welded connection. Sleeve can be provided on the welding end as needed; the valve stem lengthened buried all-welded ball valve can be provided according to the customer's working condition. The length of the stem is provided by the customer.

Structural Features:

1. The three-way ball valve can be divided into a double seat seal and a four-seat seal. The four-way ball valve is a four-seat seal design.

2 three-way ball valve In addition to the ordinary L-type and T-type structure, there is a custom Y-type three-way ball valve, the flow path of the Y-type three-way ball valve is "Y" type, and the valve seat is a three-sided valve seat. It is mainly used for the switching of the flow direction of the Y-type pipe. The Y-line three-way ball valve is divided into two types. One is a 120° three-way ball valve and the other is a 135° three-way ball valve. The 120° three-way ball valve has a flow path of 120° switching. The 135° three-way ball valve has a flow path of 135° (45°) switching. The flow path is flat, the fluid resistance is small, and the flow capacity is strong, so that the medium does not stay. Inside the pipeline, each pipe can be switched very smoothly,

3, three-way ball valve and four-way ball valve can be soft seal (PTFE, RPTFE, DEVLON, NYLON, PEEK) and spray-welded nickel-based alloy (hardness greater than HRC60) according to different working conditions, supersonic tungsten coating Advanced processes such as cobalt alloy (hardness greater than HRC70) and special hardening materials are suitable for a variety of demanding conditions.

4. The valve stem anti-flying design, that is, the blowout design, prevents the valve stem from being ejected from the valve body due to improper operation.

5, three-way ball valve and four-way ball valve have fireproof and anti-static devices.
