Bellows Valves WJ41H-16P

Bellows Valves WJ41H-16P & HSNH440Q2-46NZ Air-side Sealing Oil Pump Mechanical Seal
Product Introduction
The bellows valve (WJ41H-16P) features 16MPa pressure resistance, reliable sealing performance and strong adaptability. It is matched with the HSNH440Q2-46NZ air-side sealing oil pump mechanical seal, which requires strict control of cooling, friction and installation precision. Together, they integrate YOYIK’s professional strength to ensure long-term stable operation of power station oil pump systems.

Company Profile

Product Features & Operation Points
- WJ41H-16P: 16MPa pressure resistance, high-performance bellows sealing, compatible with oil pump system working conditions.
- Cooling control: Connect low-pressure sealing oil line for flushing; keep oil temperature ≤40℃, check cooling pipes if over 50℃.
- Precise installation: Spring compression 5-8mm (measured with depth gauge); ensure smooth contact surfaces of moving/stationary rings.
- Routine inspection: Normal leakage 1-3 drops/min; maintain immediately if leakage increases or temperature exceeds 60℃; polish/replace bushing when replacing seals.

Applications
- Matching power station air-side sealing oil pump systems, suitable for WJ41H-16P shut-off control and HSNH440Q2-46NZ seal protection.
- Applicable to power station main pump supporting equipment, extending seal lifespan to synchronize with main pump overhaul cycles.
- Ideal for power station projects pursuing low unplanned downtime, supported by YOYIK’s full-process service.
