Import Din Spring Loaded Pressure Safety Valve — Buy in Bulk from Supplier in China

The DIN spring loaded pressure safety valve from Yongjia Goole Valve Co., Ltd. is a direct-acting relief device designed to protect pressure vessels and piping systems from overpressure conditions. It operates at set pressures defined by DIN 3271 and EN 12241 standards, with nominal diameters typically ranging from DN15 to DN100 and pressure ratings up to PN40. The valve body is constructed from ductile iron or carbon steel, with internal components including a spring, nozzle, and disc made from stainless steel or hardened alloys to resist corrosion and thermal stress.

Standard materials comply with DIN 1.4301 or ASTM A216 WCB for body and trim, with optional stainless steel trim for corrosive media. The spring is calibrated to precise set pressures and features a compression range suitable for steam, air, gas, or non-corrosive liquids. Typical seating materials include PTFE or stainless steel, ensuring tight shutoff at closing pressure. These valves are commonly used in boiler systems, compressor stations, and chemical reactors where failure could result in catastrophic release.

Buyers in oil and gas, power generation, and pharmaceutical processing use these valves to meet process safety requirements. The valves are packed in wooden crates with internal foam padding, and bulk orders are shipped in palletized units. Trade terms are available under FOB Shanghai or CIF ports, with lead times of 4 to 6 weeks after order confirmation. Minimum order quantities are negotiable but typically start at 10 units per size. Buyers should confirm pressure setting tolerance and test certificates prior to shipment.
