Product Description
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).
Below is the working process for its internal structure :
1. water treatment diaphragm valves can be used in sand filters, replacing two sets of electric or pneumatic valves, easy to be controlled;
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.

ZC series BT Top entry ball valves are available in size 2~24"ANSI class rating 150 to 1500 and temperature ratings of -46 to 250 . A ll meet the fire safe requirement of BS 6755 and API 6FA.
The top entry trunnion supported design and unique seat retraction technique gives the convenience of in-line repair or replace valve internal components without dismantling it from pipe line.
Because each ball seat shuts off the line fluid independently on the upstream side, so this series ball valves are suitable for double block and bleed application. Secondary sealant injection system for stem and seat is provided for emergency stop of accidental seat or stem leakage.

Top Entry Ball Valve is mainly applicable for pipeline and industry system such as petroleum, chemical engineering and nuclear power plants. Its body adopts an integrated design, reducing leak points. Its seat design is available for either soft or hard seal, easy for maintenance. It has a top entry and on line maintenance function. It has a lot of advantages, such as small fluid resistance, simple structure, small volume, light weight, reliable sealing, convenience for operation and maintenance, open and close quickly, as well as start and close flexibly.
Its most difference from common Ball Valve is that its maintenance can be made on pipe line and without dismounting from the pipe line. The back space seat structure is adopted for the seat and the rear portion of seat retainer is oblique angle to prevent accumulation of impurity from affecting back space of seat.
It's featured by its small torque and reliable seal; and unlike common ball valve types, its seat with a spheroidal structure can adjust the seal position automatically.
