262

Sealant：262

High-Temperature Anaerobic Sealant

1. Degradation from extreme temperatures; 2. Contamination before application; 3. Incomplete curing due to improper surface preparation.

1. Clean mating surfaces thoroughly before application; 2. Allow 24 hours for full curing; 3. Use within 6 months of opening.

Valve Rubber

Nitrile Rubber (NBR) with Reinforced Fabric

1. Chemical degradation from hydraulic fluid additives; 2. Compression fatigue from repeated valve closure; 3. Aging from high-temperature exposure.

1. Use compatible fluids (per ISO 6743-4); 2. Replace every 800 operating hours; 3. Store in cool, dark environment to prevent aging.

B0308-005

Steel Ball：φ5

Stainless Steel (440C) with Polished Surface

1. Wear from contact with valve cup/seats; 2. Scratching from abrasive particles; 3. Corrosion from contaminated media.

1. Filter media to remove particles >0.1mm; 2. Inspect for scratches monthly; 3. Replace all balls if any show excessive wear (to maintain uniformity).

Should I replace the complete valve body assembly or individual parts?

If multiple parts (e.g., valve body, steel balls, valve rubber) show wear, use the complete assembly (11-3161-0511-01-00) for efficiency and compatibility. For single-part failures, replace only the damaged component—genuine parts ensure fit and performance.

How often should the steel balls be replaced?

Replace the φ5 steel balls (B0308-005) every 1,000 operating hours under normal conditions. For abrasive media, shorten to 600 hours. Always replace all 46 balls together to maintain consistent seating and prevent uneven wear.

What’s the correct way to apply 262 sealant for optimal sealing?

Clean mating surfaces with a degreaser and dry thoroughly. Apply a thin, uniform layer of 262 sealant (1–2mm) to thread or flange surfaces, avoid over-application. Allow 24 hours for full anaerobic curing before pressurizing the valve (per manufacturer specs).
