balanced cage type regulating valve

the NHCB balanced cage type regulating valve controls each kind of high temperature, the low temperature high-pressured fluid, is one pressure balance-like regulating valve. The valve structure is compact, has assumes the S streamline form the channel, but is also equipped with around an improvement sleeve the fluid balanced flowing guidance wing, causes its pressure drop loss to be small, the current capacity is big, The discharge characteristic precision is high , conforms to the IEC534-2-1976 standard. The regulating valve dynamic stability is good, low noise, small the air and the chemical etching

the regulating valve's spillage conforms to ANSI the B16.104 standard. The regulating valve uses for parts the multi-spring thin film or the air cylinder implementing agency, the structure is compact , the output strength is big.
