nylon PA6 material hydraulic water control solenoid  valve 1. water treatment diaphragm valves 2. Hydraulic or Pneumatic 3. manufacture price 4. Durable,refined water treatment diaphragm valves is lighter and rustless than those made of iron. It's added anti-aging to prevent aging after sunlight. And every valve have been pressure tested before shipment (15kg). 2. PA6 (Nylon) material, max working pressure is 1.0MPa; 3. Clamp connection, easy installation and removal; 4. Never rust, corrosion resisting, can be used in weak acid environment; 5. Good aging resistance, can be used in the open air; 6. Switch quickly, good operation stability; 7. Easy to replace parts, low maintenance costs; 8. The diaphragm is made of advanced rubber material which has good elasticity, between rubber is the imported    high strength net cloth with good rebound performance; 9. With the bilateral dovetail waterproof rubber seal ring, it prevents water leakage of operation; 10. With the hold hoop on top, it's much safer and is convenient to change the parts inside; 11. External uses professional nylon paint treatment, excellent appearance.

Carbon Steel Casting includes carbon as the main alloying element and a small amount of other elements. As the carbon content increases, the strength of cast steel increases and the hardness increases. Cast carbon steel has higher strength, plasticity, toughness, and lower cost, and is used in heavy machinery to manufacture parts that are subjected to heavy loads. Precision casting is the general term for obtaining precision-size castings. Compared to the traditional sand casting process, precision casting products are more precise in size and have a better surface finish. China precision casting is also called lost wax casting. Casting products are precise, complex, and close to the final shape of the parts, which can be used without processing or with little processing, so It is an advanced technology. In wax pattern process,we mix stearic acid and paraffin
wax in wax pattern making,as you know,it is better than polyethylene,and the
wax deformation is small. In dipping slurry process, most of the suppliers adopt
water glass technics in domestic area,but we adopt compound technics or silica
sol technics. As you know,carbon steel castings will be much smoother with
compound technics (compound of water glass and silica sol technics), and this method
is so popular with our customers. The quality is higher than water glass
technics, and the cost is lower than silica sol technics. Carbon steel precision casting divedes auto parts casting, Train Parts Casting, railway parts casting and Mechanical Precision Casting. The main casting steel material is No.25 steel, No.35 steel, and No.45 steel.
