Series 641/642/643

- Rugged Aluminum Design: Features a robust aluminum body, bonnet, and bowl coated with a specialized
powder finish that provides excellent salt spray and corrosion resistance in harsh process environments.
- Industry-Leading Flow Rates: Maximizes process valve efficiency with high-flow nominal ranges
from 2,210 to 10,500 l/min (78 to 370.8 SCFM).
- Port Sizes: Available in 1/4", 3/8", 1/2", 3/4", and 1" (NPT & G threads).
- Pressure Specifications: * Max Inlet Pressure ($P_1$): Up to 20 bar (290 psi) for manual drain.
          Adjustable Outlet Pressure ($P_2$): 0.5 to 10.5 bar (7.3 to 152.3 psi) via bolt or T-handle.
- Filtration Efficiency: Offers 5µm, 25µm, and 40µm high-capacity filter options (Polyethylene, Bronze, or
Stainless steel elements) to effectively prevent downstream contamination.
- Temperature Resilience: Standard NBR seals handle down to -40°C to +90°C, with an ultra-low
temperature version available down to -52°C.
- Safety Features: Built-in Quick Relief function (on 641 and 642 models) quickly exhausts downstream
actuator pressure if the supply air is lost.
- Certifications: ATEX (non-electrical), CRN, and UKCA certified.

Series 342A

- Durable 316L Stainless Steel Construction: Features internal and external components entirely made of
316L Stainless Steel. This rugged build provides exceptional corrosion resistance, making it ideal for offshore,
marine, chemical plants, and highly aggressive environments.
- Precise Actuator Control: Utilizes a molded reinforced diaphragm to provide highly optimized flow paths,
ensuring superior high flow rates and highly accurate pressure regulation to downstream actuators.
- Port Sizes & Compliance: Available in Compact (1/4") and High-Flow (1/4", 1/2", 3/4", 1") configurations
with NPTF threads. It is NACE compliant for sour gas applications.
- Pressure & Drainage Options: * Max operating pressure up to 11 bar
          Standard output regulating pressure of 0.5 to 10 bar (with a low-pressure 0.5 to 2.5 bar variant upon request).
- Elastomers & Protection: Standard high-performance FPM elastomers and IP65 ingress protection making it
dust-tight and water-resistant.
- Operational Features: Includes a Quick Relief option to prevent actuator locking, a safety glass integrated
pressure gauge, and a durable laser-etched nameplate to prevent fading or peeling.
