Product Description
1. Forged ball valve feature
Zhejiang Huatai forged ball valve, the forging material can ensure sufficient rigidity and strength under maximum rated operation pressure without inherent flaw of cast. Enough wall thikness of separate body and adaptation of high strength tie bolts are convenient for valve maintenance and sufficient to bear the stress of pipe. The internal parts of valve are carefully designed and selected to ensure reliability under all kinds of work condition.
2. Anti-fire safe design
When the trunnion ball valve be used normally, its sealed by seat and ball surface, seat retainer sealed by O-ring and body, this is soft sealed and reliable sealing. When the seat and O-ring are burnt, the seat retainer and body will be sealed by expanded graphite. Thus act anti-fire safe purpose.
3. Anti-static device
In order to prevent friction among ball, stem and PTFE that generates static electricity which may light the combustibles and explosives that cause an accident, in this ball valve, static-conduction spring is set between the stem and the ball, the stem and the body. Thus static electricity is conducted to ground and system safety is secured.
4. Free leakage of body Sealed construction
The connective position of valve body and bonnet is double sealed by gasket and O-ring, on this base, such factors as fire, high temperature, shock and uneven opening or closing of the torque all can't induce external leakage.
5. Low torque in operation
The self-lubricated bearings are installed at the friction of stem, resulting in wear resistance, fiexibility of operation and low torque.
6. Double block&bleed(DBB)
When ball is full open or close position, the transmitter substance in center cavity of body can be released by drainage and emptying devices. In addition, the over loaded pressure in the center cavity of valve can be released to low pressure end by self relief seat.
7. Emergency sealing
Compound injection holes are designed and compound injection valves are installed at locations of stem/cap and body support of side valve. When sealing of stem or seat is damaged to induce leakage, the compound can be used to do the second time sealing. A concealed check valve is installed in side of each compound injection valve to prevent compound from out flowing due to the action of transmitter substance. The top of the compound injection valve is the connector for fast connection with compound injection gun.
HUATAI (Zhejiang) Valve Manufacturing Co., Ltd. Locates in Linpu Road DongOu Industrial Zone Oubei Town Wenzhou City Zhejiang Province, where is usually called "Origin of China-made Valve and Pump". The transportation is very convenient Near No. 104 Highway and Wenzhou Downtown. Strictly Following the international standards (API, DIN, JIS) We have more than 20 years experience in producing ball valve.
Our main products including casted steel trunnion/floating ball valve, forged steel trunnion/floating ball valve, NPS ball valve and full-welded ball valve, etc. Especially the full-welded ball we have made great breakthrough and gained huge achievement.
The product lines cover many kinds of casting steel, casting iron butterfly, gate, check, globe valves. These products are widely applied to the petrochemical, power, metallurgy, foodstuff, paper-making construction and other industries. Addionaly, our completely self-developed special valve for spewing coal service and the large size ball valve have obtained the new product appraisal certificate, and Huatai's large size obit ball valve has contributed greatly to the National Major Project of long distance line & gas transportation pipelines.
Huatai has considered the methods of comparing and learning from the world outstanding enterprises as its perennial developing policy.
