Bürkert Type 2000 Angle Seat Valve | 00001140 00001392 00130175 | Pneumatic Process Valve

The Type 2000 Series pneumatic angle seat valves by Chengyuan Hydraulic are classic externally piloted process valves, engineered to be fully compatible with Bürkert technical standards. Covering part numbers from 00001140 to 00130175, these units offer 100% original-place interchangeability. Featuring a unique Y-pattern body, the Type 2000 provides a streamlined flow path with a $C_v/K_v$ value significantly higher than conventional globe valves. Built with premium stainless steel bodies and PTFE seals, it handles steam, water, alcohols, and mildly corrosive media with ease. Paired with high-efficiency single or double-acting pneumatic actuators, this valve guarantees sealing stability over millions of cycles.

• Control Functions: Normally Closed (NC), Normally Open (NO), Double Acting

• End Connections: G thread, NPT, Welded, or Flanged

Key Technical Advantages:

• Self-Adjusting Stem Sealing: The valve stem is sealed with a robust V-ring PTFE packing gland equipped with a compensation spring. This design ensures maintenance-free operation and zero external leakage, even under high-frequency cycles and thermal fluctuations.

• High Flow, Low Resistance Path: The Y-pattern configuration allows the fluid to flow through the valve with minimal deviation. Compared to standard globe valves, the Type 2000 reduces flow resistance by approximately $30\%$, enabling higher flow rates at lower pressures.

• Modular Actuator Versatility: The pneumatic actuator can be rotated $360\text{°}$ to simplify air line routing in tight spaces. An integrated visual position indicator on the actuator cap allows for instant verification of the valve’s status.

• Anti-Water Hammer Design: For applications prone to water hammer, we offer “flow under seat” configurations. The spring-buffered closing action prevents sudden pressure surges, protecting the integrity of downstream piping and equipment.

Application Areas:

• Food & Beverage: Steam control for sterilizers and fluid switching in CIP (Clean-in-Place) systems.

• Textile & Dyeing: Managing water and chemical lines in high-temperature dyeing machines.

• Packaging Machinery: Steam molding processes and blow molding auxiliary circuits.

Expert Maintenance Tips:

• Pilot Air Quality: While the actuator is rugged, it is recommended to install a $5\mu\text{m}$ air filter in the pilot line to prevent debris from damaging the piston seals.

• Seat Inspection: When handling viscous media (like syrups or adhesives), perform regular flushing to prevent media from hardening on the seat, which could cause incomplete shut-off.

• Torque Application: For threaded versions, use PTFE tape or suitable sealants. Avoid excessive torque during installation to prevent distortion of the valve body.
