DN Series Steco Pin-Type Mining Ball Valve – BV2MN

Steco-Type Hydraulic Ball Valve for Underground Mining Equipment

Hydraulic systems used in underground mining equipment require reliable fluid control, compatible connections and components suited to demanding operating conditions. Hydraulic valves control fluid flow by opening or closing a passage and, where the design permits, regulating flow.

Hidroman's DN Series Steco pin-type mining valve belongs to the BV2MN series of two-way hydraulic ball valves. It is designed for mining applications requiring a compatible Steco-type connection.

The locking washer on the square pin allows the valve to be secured in the open or closed position. This mechanical feature helps prevent unintended changes to the selected valve position.

Key Features of the BV2MN Steco Mining Ball Valve

Two-Way Ball Valve Design

The BV2MN series uses a two-way ball valve design to open or shut off fluid flow. Flow throttling may be possible in suitable applications, subject to the manufacturer's operating limitations. Continuous throttling should not be assumed suitable without confirmation.

Lockable Open and Closed Positions

A locking washer on the square pin allows the valve to be secured in either the open or closed position. This feature helps maintain the selected valve setting during operation.

The locking mechanism is not a substitute for a complete machine safety system or an independent means of securing hazardous loads.

Hard Chrome-Plated Steel Ball

The published product information identifies the valve ball as steel with a hard chrome-plated surface. The ball mechanism provides the valve's primary flow opening and shutoff function.

Sealing Components

The standard product description specifies an NBR nitrile O-ring and a special ball-seat sealing element. Seal compatibility should be checked against the hydraulic fluid, operating temperature and application conditions.

Steco-Type Connection

The product page specifies DIN 20043 as the connection type. Compatibility should be confirmed by checking the mating profile, dimensions and sealing arrangement, rather than relying on nominal diameter alone.

Technical Specifications

Technical note: The reviewed product page does not specify all available DN sizes, maximum working pressure, flow capacity or dimensional drawings. Confirm these details, connection compatibility and the selected seal configuration with Hidroman before ordering.

Applications for Steco Pin-Type Mining Valves

Underground Mining Equipment

Hydraulic circuits in underground mining machinery require components that match the system's operating conditions and connection requirements. The BV2MN series can be evaluated for mining hydraulic applications when its technical specifications match the intended use.

Roadheader and Coal Mining Machinery

Roadheaders and coal mining equipment may incorporate hydraulic pumps, motors, valves and specialized connection systems. Steco connection compatibility is an important factor when selecting replacement components or designing hydraulic circuits.

Fully Mechanized and Semi-Mechanized Mining Systems

Fully mechanized and semi-mechanized mining equipment requires valve selection based on circuit design, pressure, flow, fluid type, connection standard and operating temperature.

A valve's suitability should not be determined by its product family or connection type alone.

How to Select the Right Steco Mining Valve

Before selecting a valve, evaluate the following criteria:

• Nominal diameter (DN): Confirm compatibility with the pipe or hose line.

• Working pressure: The valve's approved pressure rating must meet the system's operating requirements.

• Flow rate: Consider the required flow and acceptable pressure drop.

• Connection type: Verify the Steco mating profile and DIN 20043 compatibility.

• Seal material: Select NBR or an approved alternative based on the fluid and temperature.

• Operating temperature: Confirm the limits of the complete valve and its sealing components.

• Locking requirements: Determine whether mechanical locking in the open or closed position meets the application's needs.

Frequently Asked Questions

What is a Steco pin-type mining valve?

It is a two-way ball valve used in mining hydraulic systems, featuring a Steco-type connection and a locking mechanism that can secure the valve in the open or closed position.

Which connection standard does the BV2MN series use?

The Hidroman product page specifies DIN 20043. Verify the mating profile and dimensions before ordering.

What is the operating temperature range?

The source lists −30 °C to +110 °C for the standard NBR configuration. For the Viton option, it lists −30 °C to +225 °C. Confirm the approved limits for the exact configuration before use.

What is the maximum working pressure?

The reviewed product page does not specify a maximum working pressure. Obtain the manufacturer's approved pressure rating before selecting the valve for a particular circuit.

Where can this valve be used?

It can be evaluated for underground mining machinery and other mining hydraulic systems when pressure, flow, temperature and connection requirements are compatible.
