In the evolution of water distribution, industrial, and municipal pipeline systems, the importance of gate valve 110mm and its larger (gate valve 14 inch, gate valve 150 mm, gate valve 1500) or smaller (gate valve 15 mm) variants cannot be overstated. The market for ductile iron, cast steel, and high-performance gate valves has grown significantly, emphasizing not only reliability and pressure endurance but also compliance with international standards like EN 1074-4:2000 and EN 1092-2:1997.

Recent years have seen an emphasis on enhanced internal coatings (such as 100% fusion-bonded epoxy), corrosion resistance, and the use of stainless steel fasteners (SS304/316) for longer service life. In large-scale valves like gate valve 14 inch and gate valve 150 mm, compliance with EN and AWWA standards ensures leak-tightness and structural integrity.
The global gate valve market is projected to grow at a CAGR of 4.1% between 2022-2028 (source), driven by ongoing infrastructure development and a shift towards automated operation (electric and pneumatic actuators).
Valve innovation has also focused on reducing headloss, optimizing shut-off curves, and simplifying maintenance as documented in the Renewable and Sustainable Energy Reviews.

A: The most commonly used material is Ductile Iron (EN-GJS-500-7), known for its outstanding strength and toughness, with an internal/external fusion-bonded epoxy coating for corrosion resistance. Stainless steel (SS304/SS316) options are also available for highly corrosive environments.
A: Yes, it is designed according to EN 1074-4:2000, with flange connections per EN 1092-2:1997 and tested to EN 12266-1:2012, ensuring compatibility with global piping systems.
A: The standard working pressure is 16kg/cm² (PN16), with shell test pressure up to 25kg/cm² in most ductile iron models. See trends in the visualization above for recent data.
A: The main reference standards are EN 1092-2 (flanged valves), ISO 7005-2, and AWWA C515 for large diameter valves (>DN350). Proper alignment, gasket placement, and bolt torqueing are key installation steps.
A: Routine inspection for sealing surface wear, periodic operation to avoid seizure, and checking epoxy coating integrity. The bolting (SS304/316) also needs torque inspection as per manufacturer's guidance.
A: Yes. Electric or pneumatic actuators can be fitted for remote or automated control, particularly in critical infrastructure or inaccessible areas.
A: Compared to single orifice models, double orifice designs rapidly release both large volume (air pocket removal) and small bubbles (micro-air) during pipeline filling and operation, protecting against water hammer and surges.
Our gate valve 110mm and Ductile Iron Double Orifice Air Release Valves have been widely adopted for water supply networks in Africa, Southeast Asia, and the Middle East.
Projects include municipal water expansion in Nairobi, desalination plant in Dubai, and irrigation system upgrade in Vietnam.
