DIN Soft Seal Gate Valve

Specification

DN50~DN1200 PN10~PN16 Cast Iron Rising Stem Solid Wedge Gate Valve

I. Product Overview

Valvefac cast iron rising stem solid wedge gate valve is a reliable flow control solution engineered for industrial pipelines handling water, steam, oil, and mild chemicals. Crafted with cast iron and ductile iron, it features a rising stem and solid wedge design to achieve tight shut-off and easy operation. Operating at -10℃~120℃ and PN10~PN16 pressure, it complies with API 609, DIN 3352, and AWWA standards, ensuring compatibility with global industrial systems. The rising stem design provides visual confirmation of valve position (open/closed), critical for safe operation in water treatment, chemical, and heating systems. With durable construction and strict testing, it balances cost-effectiveness and performance, making it ideal for general industrial flow control.

II. Key Attribute Parameters

Size Range: DN50~DN1200, covering small to large-diameter pipelines for diverse applications, from water supply to industrial fluid transfer.
Pressure Range: PN10~PN16 (1.0MPa~1.6MPa), adapting to low to medium-pressure systems such as municipal water networks and auxiliary steam lines.
Temperature Range: -10℃~120℃, suitable for normal and moderately heated media like cold/hot water, low-pressure steam, and light oil.
Material Configuration:
- Body & Bonnet: Cast iron/ductile iron, offering high strength and cost-effectiveness for general industrial use.
- Wedge: Cast iron/ductile iron (solid wedge), ensuring tight sealing by wedging against seats under pressure.
- Stem: Stainless steel (SS420) or brass, resistant to corrosion and ensuring smooth vertical movement (rising stem).
- Sealing Components: EPDM/NBR sealing rings and flexible graphite packing, providing reliable leak-tightness and compatibility with water, oil, and mild chemicals.
Connection Type: Flanged, with drilling conforming to DIN 2533, ANSI 125/150, and JIS 10K standards for global pipeline integration.
Actuation: Manual (handwheel), with rising stem design for clear visual indication of valve position.

Design & Test Standards: Design follows DIN 3352 F4/F5, MSS SP-70; testing complies with DIN 3230 (hydrostatic and leakage tests) to ensure performance.
