Two-Way High-Pressure Steel Block Ball Valves

Two-way ball valves open or close a single flow path with one quarter-turn of the handle — the standard configuration for shutoff and isolation service. Apex Flow Solutions offers Midland high-pressure steel block-body two-way ball valves in NPT and SAE straight-thread connections.

About steel block ball valves

Pressure, seal material, end connection and other specifications are published by the manufacturer per part number, not as one family-wide figure. Where a spec isn’t published for a given SKU, the product page leaves it blank rather than assuming it matches a similar-looking part.

NPT vs. SAE connections

NPT (National Pipe Taper) is a tapered thread used for general plumbing and process lines. SAE (SAE J514 O-ring boss) is a straight thread with an O-ring seal, common on hydraulic systems. Match the connection type already used on your line, and confirm the exact part number’s specifications before ordering.

Frequently asked questions

What’s the difference between a 2-way and 3-way ball valve?

A 2-way valve opens or closes a single flow path — it’s a shutoff valve. A 3-way valve uses an L-port ball to direct flow between two outlet paths from one inlet, so it can divert, select, or isolate a branch line. Choose 2-way for simple on/off service and 3-way when you need to switch or divert flow.

What’s the difference between NPT and SAE connections on these valves?

NPT (National Pipe Taper) is a tapered thread used for general plumbing and process lines. SAE (SAE J514 O-ring boss) is a straight thread with an O-ring seal, common on hydraulic systems. Match the connection type already used on your line; exact thread details vary by part, so confirm against the specific SKU before ordering.

Are pressure and seal specifications the same across the whole family?

No — printed pressure ratings, seal material, and other specifications are published by the manufacturer per part number, not as one family-wide figure. Where a spec isn’t published for a given SKU, we leave it blank on the product page rather than assume it matches a similar-looking part. Check the individual product page, or contact us to confirm before you order.

High-Pressure Steel Block Construction

These are steel block-body valves: steel body construction (Midland printed material), sized and threaded to match your line connection. Pressure rating, port style, seal material and other specifications vary by SKU — see each product page for the manufacturer-published values that apply to that exact part. Where a value is not published by the manufacturer, it is left blank rather than assumed.

Choosing a Two-Way Valve

Match the connection type to your system — SAE O-ring boss for hydraulics, NPT for general plumbing and process lines — and size by the line thread. Media, service and application suitability are not published by the manufacturer for this valve; tell us your fluid, temperature and working pressure and we will confirm suitability before you order.
