Additionally, the company is equipped with equipment for magnetic particle testing, an Inos spectrometer, a universal testing machine, carbon-sulfur analyzer, ultrasonic testing machine, X-ray testing machine, spring tension/compression tester, and helium mass spectrometer for material inspection.

The company currently employs 172 people for the production of safety valve products, with 29 technical personnel (including 1 senior engineer and 6 intermediate engineers). LUOFU’s safety valve products are divided into two major categories: the API series and the national standard series. The API series safety valves are designed, manufactured, and tested according to the API520, ASME I, ASME VIII, API526, and API527 standards. The national standard series is designed, manufactured, and tested according to GB/T12241, GB/T12242, and GB/T12243-2005 standards.

Product types include: spring-loaded, pilot-operated, bellows backpressure balanced, insulated jacketed for urea plants, and high-performance steam safety valves. Materials include WCB, LCB, CF8 (304), CF8M (316), CF3M (316L), 316L.mod, 304L, 304H, 310S, 321, C12A, 17-4PH, and special materials such as HC, HB, Monel, Ti, Ni, etc. The bellows material includes 316L, HC, Inconel 718, and others. The spring materials include 50CrVA, 30W4Cr2VA, 17-7PH, 316, Inconel 750, and others. The API series safety valves range from nominal pressure 150Lb to 2500Lb, with sizes from 1/2” to 20”, and the national standard series ranges from nominal pressure 1.6MPa to 42MPa, with sizes from DN15 to DN600.

Business Philosophy and Quality System

The company adheres to the business philosophy of “Customer First, Integrity-Based” and the quality policy of “Focus on Quality, Strengthen Management, Continuous Improvement, and Customer Supremacy.” The company values the product quality and needs of each customer (or project), forming project teams to coordinate design, manufacturing, and inspection to ensure timely delivery of products with the required quality and quantity. The company places great emphasis on talent selection, training, motivation, and performance assessment to create a favorable growth environment, enabling capable and ambitious employees to showcase their talents and achieve their aspirations.

The company has established a strict quality control system in accordance with the ISO9001:2008 Quality Management System requirements and the Special Equipment Manufacturing License. All personnel and processes are managed according to system documents and TS requirements. The company conducts technical problem-solving and process verification for major technical and quality issues. Key processes have been designed with quality control points to strengthen prevention and control. The company’s quality inspection system establishes three control points: incoming inspection, semi-finished product inspection, and finished product inspection, with a combination of special inspection, self-inspection, and mutual inspection. This ensures clear identification of semi-finished products, finished products, and non-conforming products in warehouses, workshops, and production lines, providing traceability for product quality.

The company has a physical and chemical laboratory and a non-destructive testing room. It can perform tests on carbon steel, alloy steel, austenitic stainless steel, duplex stainless steel, and special steel materials. Non-destructive testing methods include liquid penetrant (PT) testing, magnetic particle (MT) testing, radiographic (RT) testing, and ultrasonic (UT) testing. These methods are applied to valve bodies, welds, valve stems, springs, and other components.

To ensure product quality and meet customer requirements, the company continuously improves internal management, strengthens overall quality awareness, and is dedicated to providing high-quality products to its customers.
