1. Valve body: It is cast as a whole or processed after casting, and the internal flow channel is designed for full diameter flow.
2. Valve cover/valve cap: The upper part of the valve cover usually has a chamber that accommodates packing and pressure cover.
3. Valve plate: The metal skeleton of the gate plate is completely covered with a layer of elastic sealing material EPDM rubber, which is the key to achieving "soft sealing".
4. Seat: DIN standard: The design and dimensions of the seat must ensure compliance with DIN standards for sealing grade requirements.
5. Valve stem: 2CR13 stainless steel is the preferred choice, with excellent strength and corrosion resistance.
6. Valve stem nut: usually made of all copper, with good wear resistance and low friction coefficient.
7. Handwheel: The most common manual operation method, made of ductile iron material.
8. O-ring: Three O-ring silicone seals with wear-resistant and high temperature resistant characteristics.
9. Sealing ring: It is sealed with EPDM rubber, which has excellent wear resistance and flexibility to achieve overall compatibility.
