Farris Engineering 27CA33-M41 pressure relief valve Key Specifications

• Orifice and Sizing: C orifice designation provides 0.068 square inches for controlled flow capacity; suitable for 1″ x 1″ inlet/outlet configurations.​

• Pressure Range: Handles set pressures up to 2500 psig at standard temperatures (-20°F to 750°F), with maximum backpressure of 400 psig at 100°F.​

• Connections: MNPT inlet and FNPT outlet standard, with options for flanged, socket weld, or welding nipple adaptations.​

• Certifications: ASME Section VIII compliant for air, steam, water; National Board certified capacities.

Benefits:

• Fixed blowdown (5-15%) simplifies maintenance and testing, with a built-in lift stop for stable operation under variable conditions.
• Balanced design option nullifies backpressure effects, ideal for systems with superimposed or built-up pressure.
• High interchangeability of parts reduces downtime and costs in industrial setups like marine engineering or process plants.

​

Usage:

• Perfect for e-commerce marine equipment suppliers or automation systems needing robust pressure relief for vessels, pipelines, or high-pressure processes.
• Supports capacities like 35-52 SCFM air at 15-30 psig or 100-146 lb/hr steam, certified for safety-critical environments.
