Products Introduction

The series of valve is Sanbora which makeimprove combined with foreign advanced technology , for low temperaturecondition and special research and development , The top entry structure , can meet online service or replacementvalve trim , special structural design , making dismounting more easy ,and  further improve maintainability ofvalve . The use of advanced piston seal structure , and back pressure ringdesign , ensure the sealing reliable , when cavity  pressure abnormal rises , can make pressurerelief on request of pressure relief direction by client . The unique loosedagainst measures and reasonable  partsmaterial configuration , further enhance the overall performance and servicelife of valve . This series of valve can be widely used for liquefiednatural  gas ( LNG ) , aerospace ,metallurgical and other areas in the low temperature conditions.
