Fitur dan prinsip kerja katup bola wafer listrik
Ikhtisar Katup Bola Wafer Listrik
Definisi dan Komposisi: Katup bola wafer listrik adalah kombinasi katup bola dan aktuator listrik, using electric drive to open and close the valve.
Prinsip Kerja: Setelah menerima sinyal, aktuator listrik menggerakkan katup bola untuk berputar 90 derajat, thus cutting off or connecting the medium.
Applications of Electric Wafer Ball Valves These valves are widely used in petroleum, kimia, metalurgi, pembangkit tenaga listrik, and light industry sectors. They are suitable for automatic regulation or shut-off control of oil, air, gas, dan pulpa atau cairan berserat.
Electric wafer ball valves consist of an electric actuator and an ultra-thin ball valve. They are typically suitable for applications with limited installation space. The CHR series actuator used with these valves can directly receive 4-20mA DC or 1-5V DC control signals from computers or industrial instruments. Based on the deviation between the valve position feedback signal and the set value, the actuator drive motor undergoes intelligent step adjustment (PID control) to achieve precise positioning of the valve or other device opening. Serentak, it outputs a 4-20mA DC position feedback signal.
Fitur Katup Bola Wafer Listrik:
Resistensi Cairan Rendah: Katup bola memiliki ketahanan fluida paling rendah di antara semua jenis katup.
Kinerja Penyegelan Yang Baik: Sealing rings made of elastic materials such as PTFE (politetrafluoroetilen) ensure easy sealing.
Umur Panjang: Due to the excellent self-lubricating properties of the materials, katup bola memiliki masa pakai yang lama.
Fungsi anti-statis: Pegas dipasang di antara bola, tangkai, dan badan untuk melepaskan listrik statis yang dihasilkan selama proses pembukaan dan penutupan.
