Deskripsi Produk

Katup gerbang bellow mbentuk penghalang logam antarane medium cairan lan atmosfer liwat welding rolling otomatis, yaiku desain sing nglindhungi batang tutup saka bocor.
The bellows structure is used inside, and the lower end of the stainless steel bellows is welded to the valve stem to prevent the process fluid from corroding the valve stem. The other end is placed between the valve body and the valve cover to form a static seal. The double sealing design is more secure. If the bellows fails, the valve stem packing will also avoid leakage.
Bellows dilas menyang batang tutup kanggo njaga kinerja operasi sing stabil lan nyegah getaran batang tutup sing disebabake geter tutup tutup. Katup gerbang bellows paling cocok kanggo pipelines karo uap, flammable, mbledhos, lenga termal, kemurnian dhuwur, beracun lan media liyane.

Fitur Performance

Kaluwihan
1. Katup gerbang bellow nduweni struktur sing cukup, kinerja sealing sing dipercaya lan katon apik;
2. The sealing surface is welded with Co-based hard alloy, which is wear-resistant, corrosion-resistant, friction-resistant and has a long service life;
3. Batang tutup tempered lan nitrided ing permukaan, sing nduweni ketahanan korosi lan gesekan sing apik;
4. Desain sealing pindho diadopsi, lan kinerja luwih dipercaya;
5. Batang tutup pratondo posisi ngangkat luwih intuisi;
6. Materi saka bagean, flange lan ukuran nomer welding bokong bisa cukup dipilih miturut kahanan nyata utawa syarat pangguna kanggo nyukupi macem-macem kabutuhan engineering.

Fitur:
1. Desain sealing pindho punika bellows + tutup stem packing. Yen bellows gagal, tutup gagang packing uga bakal supaya bocor;
2. Ora mundhut adi lan mundhut energi kurang;
3. Urip layanan dawa, sing mbantu nyuda jumlah pangopènan;
4. Jog tutup medium gas adopts PTFE materi sealing alus, kang mbantu kanggo nambah sealing saka bellows gapura tutup;
5. Kursi tutup nganggo segel hard conical, sing tahan suhu dhuwur lan nduweni kedap udara sing apik;
