產(chǎn)品名稱：氣動薄膜調(diào)節(jié)閥

產(chǎn)品特點：ZJHP(M)型ZJHP型氣動薄膜調(diào)節(jié)閥由氣動多彈簧薄膜執(zhí)行機構(gòu)和低流阻直通單座閥(套筒閥)組成，單座閥閥體直通單座蓋上導(dǎo)向結(jié)構(gòu)，閥芯為柱塞型結(jié)構(gòu)，與普通單座閥相比具有體積小，重量輕，流量大等特點適用于流量大，泄漏量要求嚴格的場合。ZJHM型精小型套筒與普通套筒閥相比，具有體積小1/3，重量輕1/3，流量大1/3的特點，廣泛應(yīng)用于要求噪音低、壓差大的工業(yè)過程自動控制系統(tǒng)中。

Product model: ZJHP ( M )

Product Name: pneumatic diaphragm regulating valve

Product characteristic: ZJHP ( M ) ZJHP pneumatic diaphragm regulating valve by pneumatic spring diaphragm actuator and low flow resistance through single-seat valve ( sleeve valve ), valve seat valve direct single seat cover guide structure, the plunger type structure, and the ordinary single-seat valve compared with small size, light weight, flow characteristics applicable to large flow, leakage demanding situations. ZJHM type precision small sleeve sleeve valve compared with ordinary, has small volume 1 / 3, weight 1 / 3, 1 / 3 flow characteristics, widely used in the requirements of low noise, large pressure difference of industrial process control system.
