BKH-SAE-FS, MKH-SAE-FS Series High-Pressure Ball Valve (with SAE Connector)

I. Product Introduction

This product is a 2-way high-pressure ball valve, available in BKH and MKH series specifications, suitable for standardized flange pipeline connection configurations. The valve body is compatible with SAE J518C-3000PS flange and SAE J518C-6000PS flange dedicated pipe connectors; customized flange structures can be provided, interchangeable with JB/ZQ4187-97 split high-pressure flanges, suitable for various high-pressure pipeline connection installations.

II. Development Overview

High-pressure ball valves appeared in the 1950s. With industry technology iteration and upgrading, valve body production processes and internal structures have been continuously optimized and improved, with rapid industry development. After 40 years of industry iteration, it has now become a mainstream valve product for industrial pipelines, with strong versatility and wide application scenarios.

III. Working Principle

The high-pressure ball valve uses the valve stem to drive the ball opening/closing component, rotating around the valve stem axis as the center. By rotating the ball to change the position of the internal flow port, pipeline medium conduction and cut-off are achieved, completing oil circuit and gas circuit on-off control. The valve body has small rotary opening/closing resistance, convenient operation, and reliable sealing.

IV. Pipeline Adapter Flange Specifications

1. Standard adapters: SAE J518C-3000PS flange and SAE J518C-6000PS flange matching pipe connectors;

2. Interchangeable adapters: Custom flanges can be compatible with JB/ZQ4187-97 split high-pressure flanges, with high pipeline connection versatility.

V. Product Structural Features

2. High standardized flange adaptability, American standard flanges and national standard split high-pressure flanges can be adapted, with strong interchangeability;

3. Light and convenient opening/closing operation, ball rotary opening/closing, fast open/close speed, excellent high-pressure sealing and anti-leakage performance;

4. Mature industry technology, after years of structural improvement, pressure-resistant and wear-resistant, suitable for long-term use in hydraulic, gas and other industries;

5. 2-way straight-through structure, smooth medium flow, small pipeline pressure loss, suitable for high-pressure fluid fast on-off control.

VI. Core Applications

Widely used in hydraulic machinery equipment, hydraulic control circuits, and natural gas transportation pipelines, for high-pressure pipeline medium on-off and oil circuit opening/closing control, commonly used with high-pressure hydraulic pipelines and energy storage auxiliary oil circuits as complete sets.

VII. Usage Precautions

1. Select BKH or MKH series, verify pipeline flange standards and pressure ratings before selection and installation;

2. Ensure flange connection end faces are flat and free of impurities, tighten bolts diagonally and evenly to prevent oil leakage and air leakage at high-pressure interfaces;

3. Rotate the valve stem at uniform speed to open/close the valve; do not violently wrench the valve stem to avoid ball misalignment and seal damage;

4. Regularly check valve body sealing performance, replace worn seals promptly to maintain high-pressure anti-leakage effect;

5. Clean the valve cavity before installation to ensure no impurities enter, preventing ball surface wear.
