When pressure must be controlled, failure is not an option. CHOWHANG Safety Valve has built its reputation on one simple promise: delivering reliable, high-performance safety valves that protect people, equipment, and processes across the most demanding industries.
A Full Range of Safety Valve Solutions
Every system is different, and so are its pressure protection needs. CHOWHANG offers a comprehensive product lineup to match virtually any application:
Spring-Loaded Safety Valves— The industry workhorse. Simple, robust, and dependable, these valves provide automatic overpressure protection for a wide range of steam, gas, and liquid services.
Pilot-Operated Safety Valves— Designed for high-pressure and large-capacity applications, pilot-operated valves deliver precise opening and tight seating, even under extreme operating conditions.
Bellows Safety Valves— Ideal for applications where back pressure is a concern. The bellows design isolates the disc from back pressure effects, ensuring consistent set pressure and reliable performance.
Threaded Connection Safety Valves— Compact and easy to install, these valves are perfect for smaller pipelines, instruments, and equipment where space is limited and quick maintenance matters.
Whatever your medium — steam, air, gas, water, or chemical fluids — CHOWHANG has a safety valve engineered to handle it.

Certified Quality You Can Trust
A safety valve is a critical last line of defense. That is why CHOWHANG has invested heavily in achieving the certifications that matter most to our customers worldwide:
ISO9001 Quality Management System— Our manufacturing processes are governed by a rigorous, internationally recognized quality framework, ensuring consistency from raw material to finished product.
TS Special Equipment Manufacturing Certificate— This Chinese certification confirms that our safety valves meet the strict safety and technical requirements for special pressure equipment.
EAC Certification— Our products comply with the technical regulations of the Eurasian Economic Union, opening the door to Russia, Kazakhstan, Belarus, and other member markets.
CE PED Certification— Conformity with the European Pressure Equipment Directive means CHOWHANG safety valves are approved for sale and use throughout the European Union and beyond.
These certifications are not just logos on a brochure. They represent independent verification that our valves meet the highest international standards for safety, performance, and manufacturing quality.
Built on Expertise, Priced for Value
Behind every CHOWHANG valve is a team of veteran engineers who have spent decades in the safety valve industry. Their expertise drives our design, testing, and continuous improvement. And because we own our factory buildings, source materials from ISO9001-certified suppliers, and export directly through our own Shanghai trading company, we keep costs down without ever compromising on quality.
