Ball Screw Gate Valves

Ball Screw Gate Valves are essential components in various industrial applications, known for their robustness and high performance. These valves include ball screw operators that significantly reduce operating time and ensure reliable isolation of fluids.

Features and Specifications

1. Structure

The body and flanges are integral (non-welding), ensuring a sturdy construction. Every part of the valve undergoes shot blasting and phosphating to enhance corrosion resistance.

2. Design

The valve features a ball screw structure that lowers operating time. The stem structure is pressure balanced and includes a switch indicator for easy operation.

3. Specifications

The ball screw gate valves are designed for large bore high-pressure systems. Key specifications include:

• Working pressure: Varies between PSI-PSI
• Connection types: Flange, Thread, Union, BW
• Sizes: Ranges from 1 13/16" to 7 1/16'
• Working temperature: Various classes including K, L, P, R, S, T, U, V
• Material Class: Options include AA, BB, CC, DD, EE, FF, HH
• Specification Level: From PSL1 to PSL4
• Performance Requirement: PR1 and PR2

Application Areas

1. Oil and Gas Industry

Ball screw gate valves are predominantly used in wellhead assemblies for high-pressure oil wells. They are crucial during frac operations to isolate the fluid from the well.

2. Chemical Industry

These valves are also suitable for various applications within the chemical industry, providing reliable fluid control and isolation in some of the most challenging environments.

API6A Frac Valve Ball Screw Operated (BSO) Gate Valves

Overview

Frac Valves are Ball Screw Operated (BSO) and serve as high-pressure isolation valves installed on wellhead platforms. They are the primary component of a Frac Tree and are often fitted to isolate fluids during frac operations. Capable of multi-staged fracs, they are designed to withstand the toughest environments.

Design and Operation

Qihang’s Frac Valves/Ball-Screw-Operated (BSO) Gate Valves feature flanged or studded end connections. These valves can be operated manually or with variable drive motors and actuators. With a bi-directional design, they offer flexibility in the flow direction of the hydrocarbon stream, making them ideal for use in shale plays.

Standards and Compliance

All Frac Valves produced by Qihang adhere to API 6A, API Q1, and NACE MR-01-75 standards, while also conforming to ISO regulations. They are available in various bore sizes, from 3-1/16" to 9", and capable of handling different working pressures. The standard material is integral forged AISI alloy steel, with other materials available upon request.
