Product Introduction

Product Overview

Our DN100 PN16 Gate Valve combines a high-strength ductile iron body with a resilient EPDM-coated wedge for critical industrial and municipal pipelines.

The rising stem design provides instant visual confirmation of the valve's open/closed status, making it ideal for fire protection (sprinkler systems), emergency water isolation, and pump rooms where operational safety is paramount.

Technical Features

Offers instant, visual confirmation of the valve's open/close status via the rising bright zinc-plated stem, eliminating guesswork in dark pump rooms or emergency situations.

Features a fully vulcanized EPDM resilient wedge that achieves reliable bi-directional sealing to prevent internal bypass leakage.

Cast from robust ductile iron (QT450-10), delivering significantly higher impact and tensile resistance compared to standard grey iron valves.

Protected inside and out with a fusion-bonded epoxy coating (≥ 250 microns) that satisfies WRAS requirements for drinking water safety and corrosion prevention.

Field Applications

Our OS&Y gate valves are engineered for heavy-duty isolation in critical sectors:

Fire Protection Infrastructures

High-visibility rising stems perfectly match international fire-sprinkler and hydrant line codes.

Water Treatment & Distribution

WRAS-compliant lining makes it safe for municipal potable water networks and filtration plants.

Industrial Pump Stations

Resilient seating prevents water hammer damage and internal bypass in high-velocity pump discharge setups.

HVAC & Cooling Towers

Excellent thermal stability and corrosion resistance in commercial chilled water loops.

Shipping & Supply Capability

Export Packaging

Valves are securely packed in seaworthy, fumigation-free plywood cases with inner moisture-proof linings to protect the epoxy coating during transit.

Supply Stability

Reliable production lines ensuring a stable monthly output of 10,000 pieces for the DN100 size.

Shipping Documents

Full commercial invoices, packing lists, Certificates of Origin, and Mill Test Certificates (MTC) are provided with every batch for hassle-free customs clearance.

FAQ

Q: Are your DN100 PN16 gate valves fully compliant with European standards?

A: Yes. They are designed and manufactured strictly to EN 1171 / DIN 3352 standards, with face-to-face dimensions perfectly meeting EN 558 Series 14 (F4) for direct pipeline interchangeability.

Q: Do you test every single valve before shipment, or just do spot checks?

A: We practice 100% individual hydrostatic testing on automated test benches; random sampling is strictly prohibited. In full compliance with EN 12266-1 standards, every single DN100 valve undergoes a 2.4 MPa hydrodynamic shell test and a 1.76 MPa seat leakage test before final sign-off.

Q: Is the epoxy coating safe for drinking water applications?

A: Yes. The fusion-bonded epoxy coating (minimum 250 microns thick) complies with WRAS requirements, ensuring it is non-toxic and safe for potable water systems.

Q: Can we replace the stem packing while the valve is installed under pressure?

A: Yes. Because this is an OS&Y (Rising Stem) valve with an engineered backseat design, you can fully open the valve to engage the backseat, allowing for safe packing maintenance while the valve is fully open. However, following standard site safety protocols, depressurizing the line during maintenance is always recommended.

Q: What is your standard lead time for a full container load (FCL)?

A: Our standard lead time is 20 to 30 days, supported by a stable factory monthly output of 10,000 pieces for the DN100 size.

Q: Do you support OEM branding and custom logos?

A: Yes. We offer custom logo casting on the ductile iron valve body and customized aluminum tags for bulk wholesale orders and engineering distributors.
