Product Description
Material: Cast Iron Structure: Swing Function: Ddcv Double Lobe, Nrvr Silence, Sfcv Rubber Lobe, Nrvz Silence, Nrvg Silence Flow Direction: Reversing Application: Industrial Usage, Water Industrial Usage, Household Usage Origin: Shanghai Connection Form: Thread Pressure: High Temperature Sealing Form: Gland Packings Globe Valve Standard: ANSI Trademark: DBV HS Code: 8481804090 Product Description Rubber Lined Flanged Swing Check Valves
Product Features Reasonable structure, reliable sealing, excellent performance, nice appearance. Alloy steel material is surfacing welding on the sealing face which has good characteristic against corrosion, erosion and abrasion to extend the valves' life time. It can be installed horizontally or vertically; easy installation. Quickly open and close, and wonderful sealing performance. Used as the controlling device to prevent the medium from back flowing on pipeline, carrying water, stem, oil, nitric acid, acetic acid and oxidant medium, etc. , depending on the following medium to open and close automatically.
1,DBV Company Profile-General Information DBV Brief introduction We DBV, standing for Designing, Building and Verifying, founded in 2001, set up two factories in Shanghai Baihe Industry Zone and Wenzhou Anfeng Industry Zone.

1.3 DBV Qualification
1.4 DBV Business scope
Manufacturing, processing and selling valves of ball valves, butterfly valves, gate valves, globe valves, check valves, water control valves, high temperature and pressure station valves, control valves, etc., importing and exporting of goods and technologies.
1.5 DBV Core technology
Triple offset Butterfly Valve, fully metal seated Ball Valve with zero leakage
2. DBV Performance of Main Products
2.1 Ball Valve characteristics
2.1.1 The fluid resistance is small.
2.1.2 Structure is simple, with small volume and light weight.
2.1.3 Reliable, good sealing
2.1.4 Easy to operate, quick open and close.
2.1.5 Easy maintenance, convenient to replace the ball or sealing ring.
2.1.6 In the fully open or close, the all sealing will not be corroded by the medium.
2.1.7 Wide application, from small to several millimeters, from high vacuum to high pressure.
2.2 Triple offset butterfly valve characteristics:
2.2.1 Elastic property of composite metal sealing ring performs zero leakage.
2.2.2 Torque sealing ensures the valve persistently bi-direction zero leakage.
2.2.3 Triple offset principle makes the design of 90 angle rotation with no friction, eliminating the friction between the seat and sealing ring.
2.2.4 One-piece Stellite hard seat can adopt to many working situations, long service life and easy maintenance.
2.2.5 One-piece body , with face to face dimensions conforming to ISO5752, ASME B16.10 and API609, can replace to high performance butterfly valves or Other types of valves, easy and flexible installed.
2.2.6 Fireproof in favor of metal seat and zero leakage.
2.2.7 Safe and reliable of anti-blowout stem.
2.2.8 The disc position is indicated by the indicator on the stem and the flange on the top.
2.2.9 The stem is one-piece shaft, with the stem and disc connected by pin-key combination.
3. DBV Production
4. DBV Inspection and Test - ITP According to standard API 6D & JB/T 9092-1999
DBV exports to all over the world
With experience and top-rank valves, we export to more than 30countries as England, Spain, Portugal, Russia, Thailand, India, Indonesia, Austria, Australia, Canada, Germany, France, Singapore, Finland, Iceland, Poland, Belgium, Italy, Romania, etc.
