BKH Ball Valve for High-Pressure Shut-Off
Carbon steel and stainless steel block ball valves with threaded, compression and weld-fitting connections
The Eagle Fluid BKH ball valve is a block-body shut-off valve for hydraulic oil, lubricating oil and other compatible media. Carbon steel and 304/316L stainless steel versions are available.
Choose G/BSPP or NPT female threads, compression, weld-fitting or metric 24-degree cone connections from the model tables. Pressure and temperature limits depend on the selected size, connection and complete body/seat/seal combination.
For suitable gas service, select the BKH-B stainless steel configuration and check the separate gas pressure limits.

- 小标题: Carbon steel and stainless steel block ball valves with threaded, compression and weld-fitting connections
Eagle Fluid BKH ball valves provide shut-off for hydraulic oil, lubricating oil and other compatible media. Choose carbon steel, 304 or 316L stainless steel, with G/BSPP, NPT, compression, weld-fitting or metric 24-degree cone connections. Match the exact model, seal combination and pressure rating to the operating conditions; select the BKH-B configuration for suitable gas service.

Torque Curves
The working torque of ball valve depends on pressure and ball seat sealing material. For the diagram below, working medium is water, and seal material is POM. Torque is 1.4 times that of POM supposing sealing material is PEEK, 0.8 times for oil, 1.3 times for air, and 1.4 times for granular powder. Actuator torque = 1.2*Torque (1.2: safety factor).
Ball Valves with Lock
EAGLE's BKH series ball valves can provide a locking hole to protect the open/closed status of critical ball valves. The lock needs to be purchased by customers separately.
Please add "Av" to the end of the ordering number placing an order with locking structure, for example: BKH-G1-25-4425-AV
How to select a BKH ball valve
Start with the medium, operating pressure, temperature and required connection. The BKH series uses a square block body and offers different material and seal combinations. The exact ordering code determines the configuration, so compare the complete model with the specification tables rather than selecting only by the series name.
Carbon steel or stainless steel
For hydraulic oil and lubricating oil, the listed carbon steel combination 1123 uses a 45# carbon steel body, POM ball seats and NBR seals. The stainless steel range includes 304 and 316L bodies. The listed 6665 combination uses a 316L body, PEEK seats and FPM seals for suitable higher-temperature or chemically compatible service. Confirm chemical compatibility using the actual fluid composition, concentration and operating conditions.
The temperature figures for individual metals and seal materials are not the operating rating of every assembled valve. All wetted materials, the selected seal combination, pressure and application must be checked together.
Match the connection and tube dimensions
Choose the connection that matches the existing pipework or equipment:
- G/BSPP female thread: identify the parallel thread size and the required mating seal.
- NPT female thread: use the correct tapered-thread counterpart and installation method.
- Compression connection: specify the tube outside diameter and the listed ISO 8434 light (L) or heavy (S) series.
- Weld fitting: provide the tube outside diameter and wall thickness used in the model table.
- Metric 24-degree cone: check both the metric thread and tube dimensions, including the L or S series.
G/BSPP and NPT threads are different connection systems. The same nominal size does not establish interchangeability. For help identifying the thread, see the G, Rc and NPT connection identification guide, then confirm the BKH connection against this page's model table.
Check liquid and gas pressure limits separately
Working pressure varies with nominal size, connection and configuration. The body pressure table has separate liquid and gas limits, while individual connection tables list their own model ratings. Check all limits relevant to the ordered assembly and obtain confirmation for the actual duty. A series-level maximum must not be applied to every threaded, compression or weld-fitting model.
BKH-B is the stainless steel gas-service configuration. Specify whether the medium is a liquid or a gas when requesting a quotation; do not substitute the standard liquid configuration solely because the port size is the same.
Specify mounting and locking requirements
If actuator mounting holes are required, ask for the applicable -D option and confirm the mounting-hole code for the selected size. An AV locking provision is also available; the padlock is purchased separately. For an actuated assembly, provide the operating conditions so the valve and actuator can be selected together.
BKH ball valve questions
Does every BKH model have the same pressure rating?
No. Use the pressure rating for the exact size, connection and liquid or gas configuration. A rating shown for one connection must not be transferred to another model.
Which version should I use for hydraulic oil?
The listed 1123 carbon steel/POM/NBR combination is intended for hydraulic and lubricating oils. Check the fluid compatibility, temperature and model-specific pressure limit before ordering.
Can a BKH ball valve be supplied in stainless steel?
Yes. The range includes 304 and 316L stainless steel body options. Select the complete body, seat and seal combination to suit the medium and operating temperature.
What should I send for model selection?
Provide the medium, liquid or gas duty, normal and maximum pressure, temperature range, required flow or DN, connection standard and size, tube dimensions where relevant, body/seal preference, and any mounting or locking requirement. If replacing an existing valve, include its full model code and drawing.
