Widely trusted in European process industries, power generation, municipal engineering, and oil & gas pipelines, it balances DIN standard compliance, operational efficiency, and electric control convenience for critical medium-high pressure applications.

Key Features & Advantages

1.Premium WCB Cast Steel Construction

Manufactured from ASTM A216 WCB carbon steel (equivalent to EN 10222-2 P250GH), with chemical composition: C ≤0.25%, Mn 0.50-1.00%, Si 0.15-0.40% ; mechanical properties: tensile strength 485-655 MPa, yield strength ≥275 MPa, elongation ≥20% . The cast structure ensures uniform wall thickness per DIN 3352 standards, complying with PN40 pressure-temperature ratings (EN 1092-1 Table 1) and capable of withstanding cyclic pressure loads. WCB offers excellent cost-effectiveness while maintaining structural integrity, making it the preferred choice for DIN-standard valves in non-corrosive industrial environments up to 425℃.

2.DIN/EN Standard Compliance

Fully adheres to DIN 3352 (German standard for cast steel gate valves) for structural design, DIN 3202 for face-to-face dimensions, and DIN 3230 for testing requirements . Flanged connections comply with EN 1092-1 Type 11 (weld neck flange) and DIN 2503 (PN40 flange dimensions), ensuring seamless compatibility with European pipeline systems . Meets EN 12266-1 leakage standards (Class IV) and ISO 15848 fugitive emissions requirements, guaranteeing reliability in European industrial safety regulations. The standard-compliant design enables global interchangeability with DIN-certified valves.

3.PN40 (4.0 MPa) Medium-High Pressure Rating

Rated for working pressure up to 4.0 MPa (580 psi) at ambient temperature, with pressure-temperature ratings aligned to EN 1092-1 and DIN 3352 specifications . At 300℃ (572°F), the valve retains a working pressure of 3.1 MPa (450 psi), ensuring stable performance in medium-high pressure systems such as boiler feedwater lines, process pipelines, and steam distribution networks . The reinforced WCB body and precision-engineered internal components handle pressure fluctuations without deformation or leakage.

4.EN 1092-1/DIN 2503 Flanged Connections

Equipped with flanged ends per EN 1092-1 Type 11 (weld neck) and DIN 2503 (PN40), featuring Form B (Raised Face) sealing surface . Compatible with 304+graphite or spiral wound gaskets, the RF face ensures reliable sealing against pressure variations. The flanged design facilitates easy assembly, disassembly, and maintenance — critical for periodic inspection of industrial valves — and is available in sizes from DN20 to DN400 (3/4" to 16") .

5.Electric Actuator for Remote Control

Integrated with a heavy-duty electric actuator (AC220V/380V or DC24V) designed for DIN-standard valves, featuring output torque of 100~2000 N·m (customizable for large sizes), full-stroke time of 5~30 seconds, and support for on-off or proportional control (4-20mA signal) . With IP67 protection class, the actuator is dustproof and waterproof, integrated with overload protection, limit switches, and manual emergency override — ideal for unattended or hazardous areas in European industrial plants . Direct mount design (per DIN 3337) ensures easy installation and alignment with the valve stem.

6.Full-Port OS&Y Design for Efficiency & Safety

Features a full-port flow channel that minimizes pressure drop by up to 30% compared to standard-bore valves, optimizing energy efficiency for bulk fluid transfer . The OS&Y (Outside Screw and Yoke) rising stem design keeps threads isolated from media to avoid corrosion, extending service life, while the visible stem position provides clear open/closed indication for operational safety . The rigid wedge disc with precision-machined seating surfaces (13Cr or Stellite 6 overlay) ensures tight metal-to-metal sealing (EN 12266-1 Class IV) .

7.Low-Maintenance Bolted Bonnet Design

Bolted bonnet construction with a backseat design allows in-line maintenance — inspection, repair, or replacement of internal components (stem, disc, seat) — without removing the valve from the pipeline . Key components include forged 2Cr13 stainless steel stem (ASTM A182 F6a), high-strength bolts (DIN EN 14399-4 Grade 8.8), and flexible graphite packing for reliable stem sealing . All wetted parts are manufactured from WCB or corrosion-resistant alloys, ensuring long service life in non-corrosive environments.
