SIGMA Valves在四十多年前開始生產(chǎn)專門用于石油和天然氣行業(yè)的不銹鋼氣動(dòng)和液壓控制閥。SIGMA Valves起源于專門為海上環(huán)境中的安全系統(tǒng)自動(dòng)化而設(shè)計(jì)的閥門，而不是用于石油/天然氣行業(yè)的工業(yè)閥門。與小型工業(yè)型閥門相比，這些閥門具有更強(qiáng)大的設(shè)計(jì)特性和可靠性。
SIGMA主營產(chǎn)品有：
自動(dòng)繼電器

SIGMA閥20HM系列介紹
20HM **系列三通NC閥是一個(gè)二位三通常閉，低先導(dǎo)供應(yīng)壓力操作的液壓流量控制閥組件。 它的設(shè)計(jì)目的是在每次使用相對(duì)較低的先導(dǎo)供氣壓力時(shí)自動(dòng)建立高壓液壓油輸出。
先導(dǎo)供應(yīng)壓力的損失將阻塞液壓供應(yīng)（入口）端口，并耗盡高壓接收控制回路內(nèi)的累積工作壓力。 液壓接口（接口閥）通常用于控制表面控制的子表面安全閥（SCSSV）或表面安全閥（SSV）的打開/關(guān)閉操作順序。
The 20HM** Series 3-Way NC valve is a two position, threeway normally closed, low pilot supply pressure operated,hydraulic flow control valve assembly. It is designed to establish high-pressure hydraulic fluid output, automatically with each application of relatively low Pilot Supply pressure.
A loss of Pilot Supply pressure will block the hydraulic Supply (inlet) port and exhaust the accumulated operating pressure within the high pressure receiving control circuit. Hydraulic Interfaces (Interface Valves) are generally used to control the open/close operating sequence of Surface Controlled SubSurface Safety Valves (SCSSV) or Surface Safety Valves(SSV).
