What is the maximum operating pressure for the Hydraulic two-way valve with metric external thread, type BKH L/S?

The maximum operating pressure for the Hydraulic two-way valve with metric external thread, type BKH L/S depends on the series: L (light) and S (heavy). The product description does not state explicit numeric pressure ratings; however, since it is designed for high-pressure hydraulic installations and offered in a light and a heavy series, the S (heavy) version will have a higher maximum operating pressure than the L (light) version. For the exact maximum operating pressure values for BKH L and BKH S, please consult the manufacturer's datasheet or contact the supplier with the valve type: Hydraulic two-way valve with metric external thread, type BKH L/S.

How do I choose between the L (light) and S (heavy) series for the Hydraulic two-way valve with metric external thread, type BKH L/S?

Choose the series based on required pressure rating, mechanical robustness and installation demands: - Select the L (light) series when your application has lower operating pressures, lighter mechanical loads and you prioritize compactness or cost-efficiency. L is suitable for standard hydraulic circuits where extreme stress is not expected. - Select the S (heavy) series when you need higher strength, greater durability under heavy duty or frequent cycling, or when the system is exposed to higher mechanical stresses. S is preferable for demanding, high-pressure hydraulic installations. Both versions share the same materials and seals (steel body/ball/stem, PA ball seal, NBR stem seal) and the same temperature ranges (PA: â40 Â°C to +100 Â°C; NBR: â20 Â°C to +100 Â°C). Verify your systemâs maximum pressure and duty cycle to make the final choice for the Hydraulic two-way valve with metric external thread, type BKH L/S Format.

What are the compatible fluids for the Hydraulic two-way valve with metric external thread, type BKH L/S?

Hydraulic two-way valve with metric external thread, type BKH L/S is compatible with hydraulic fluids that are chemically and physically suitable for its materials and temperature range. Recommended fluids: - Mineral oil-based hydraulic fluids (HLP/HVLP). standard compatibility with steel body and NBR stem seals; suitable across the full temp range (-20Â°C to +100Â°C for NBR; -40Â°C to +100Â°C for PA). - Water-glycol and synthetic ester fluids. generally compatible with steel; verify compatibility with NBR seals (some formulations can cause swelling or hardening). Use only if manufacturer confirms NBR compatibility. - Phosphate ester fluids (fire-resistant). may be acceptable for steel components but often incompatible with NBR; require seals rated for phosphate esters (consult manufacturer before use). - Biodegradable synthetic fluids (e.g., HETG, HEES). possible compatibility with steel; check NBR and PA resistance to the specific fluid type. Not compatible/unrecommended: - Pure water or steam (causes corrosion of steel). - Fluids containing strong acids/alkalis or aggressive solvents (can damage NBR and PA seals). - Fluorinated fluids without confirmation (may attack seals). Guidance: - Primary selection: mineral-oil-based hydraulic fluids (HLP/HVLP) are the safest, fully compatible choice. - If using synthetics, fire-resistant, or biodegradable fluids, confirm chemical compatibility with NBR (stem) and PA (ball) seals and verify viscosity-temperature behavior within -40Â°C to +100Â°C (PA) / -20Â°C to +100Â°C (NBR). - For critical applications, consult the valve manufacturer with the exact fluid specification to confirm compatibility.
