Product Overview

The Lapar Control Valve is engineered for durability and safety in challenging industrial environments, delivering reliable flow and pressure control for critical processes. With robust pneumatic or electric actuators and a rugged design, it excels in handling aggressive media, high pressures, and extreme temperatures. Certified for hazardous areas with optional ATEX compliance, the valve ensures safe operation in oil and gas, chemical, and pharmaceutical applications. Its field-serviceable construction and high shut-off performance minimize leaks and maintenance, making it a trusted choice for process automation and safety-critical systems.

Key Features
  • High Durability: Built with corrosion-resistant materials like 316L stainless steel and duplex alloys.
  • Safety Certifications: Optional ATEX certification for explosive atmospheres.
  • Reliable Actuation: Pneumatic or electric actuators ensure consistent performance.
  • Zero Leakage Option: Class VI shut-off for critical applications requiring tight sealing.
  • Extreme Condition Resilience: Operates in temperatures from -50°C to 450°C and pressures up to 100 bar.
  • Field-Serviceable Design: Simplifies maintenance with minimal downtime.
  • Anti-Cavitation Trims: Reduces wear in high-pressure differential applications.
  • Global Standards Compliance: Meets ASME B16.34, API 598, and PED requirements.
