Brass has excellent CNC Machining Turning performance, high-speed machining turning under the brass can get excellent surface finish. Our technical team has very good experience in Machining Brass, machining brass including brass plate, brass rod, brass tube. Brass hardware parts has high strength, good plasticity in hot state, good plasticity in cold state, good machinability, easy welding and good corrosion resistance. Brass parts are very durable. It is electrically conductive and does not usually corrode or deteriorate over time. Thus brass is often used to produce products with longer service life. Machining brass parts Widely used: pipes, radiators, ship parts.

US HANOVER pressure self-sealing valve features
HANOVER - Pressure Self-sealing Valve Features HANOVER valve in the United States pressure from the seal at the valve cover, the use of modular structure to achieve a linear seal, while the ring with a low-carbon steel overall silver-plated, the use of good material, anti-cavitation, and more Extended service life ensures that there is no leakage of the valve seal at high pressure drops, while other manufacturers typically use face seals or low carbon steel. HANOVER valves in the 2500-pound level and above, the body cavity and the seal contact with the Department of welding stainless steel lining deposited to avoid the body sealing area under high pressure drop under the erosion caused by soda point pitting, and thus even more assured Valve safety, long-term operation. The United States HANOVER due to the use of full-flow design, so the same size of the valve case, the valve inside the beam diameter beam design is much larger. This greatly reduces pressure loss through the valve body, reducing operating costs and increasing the thermal efficiency of the entire plant operation. HANOVER valve in the sealing performance, plus Stellite alloy welding of the rear seat seal. Once the packing leakage, as long as the valve hit the fully open position, so that the role of sealing the rear seat seal valve. You can eliminate the leak, wait until the overhaul downtime to re-replace the new packing. The United States Hannover valves for high-grade large-diameter valve with a perfect parallel valve disc combination structure. Lined with 4 high-temperature alloy steel springs. To ensure that the valve seat in a substantial increase in self-sealing temperature tight. HANOVER valves at the low-level, the wedge flap with flexible gate, this gate with fully guided central axis design. Base surface can be relative movement. And compensate for thermal bulges or pipe loads caused by deformation. Valve seat surface and the valve plate surface mounted at a 5 degree angle to reduce the valve plate and seat opening and closing the sliding contact between the two. Flexible gate design to prevent the hot open and cold state when the adhesion. Surface hardening treatment greatly enhance the service life. HANOVER valve bracket with a combination of patented structure, you can easily removable actuator, itself can be a special tool for removable bonnet seals, from the structure to ensure that the valve seal parts will not be damaged due to demolition and maintenance damage , To the user at the scene brought great convenience. The general manufacturers still use the overall casting structure. HANOVER valve design, manufacturing and quality inspection fully respect the United States ANSIB16.34 and MSS-SP16 and other international standards. The entire production and after-sales service by IS9001 and other series of international quality standard system control; ASME also issued by the production of nuclear-level valve permit. Hannover Valves selects the most advanced AUMA, LIMITORQUE, SIPOS and OTORK products on the electric actuator. AUMA electric head adopts the latest AUMASAR series products. LIMITORQUE We choose the advanced L120 series electric head which has the advantages of small output, Large, off time is short. HANOVER valve in order to strictly control the quality of all valves and actuators and all attachments are made in the United States and the overall inspection; and its strict implementation of the ISO9001 quality assurance standards, regular inspections to ensure that all parts of the quality and performance of local original guarantee. Hanover valves are 100% multi-pressure tested at the factory; due to the precision of their manufacturing equipment, the hydraulic test improves the leakage test to the factory level.
