The ZXM type new serial pneumatic membrane collet regulating valve
is a kind of pressure balancing regulating valve. Worthy of using
the executive body of many springs, overall organization's
compactness , light, the stability is good. Fluid passway
streamlined to present S, is it lower loss to be light to keep, is
it pigeonhole difference to be heavy , with low noises to allow,
circulation ability is great. Apply to control such medium craft
parameters as the gas , fluid ,etc. to keep accurately in setting
value extensively. Especially suitable for allowing the flow to be
large , pressing difference greatly, the occasion of expecting much
of letting out amount.
Series of products this have standard type and regulate person who
cut off , corrugated pipe sealed type , insert suit keep type many
kinds of variety warm. The grade of nominal pressure of the
products is PN10, 16 , 40 , 64; Valve body requirements range DN20
valve is 200. Suitable fluid temperature from- 200 suitable +560
degrees Centigrade, many kinds of grade in its range. The letting
out amount standard has IV grade or VI grade. The flow
characteristic is linear or when percentage. The varied variety
specification is available. | | Characteristic of the products: |
Adopting the balance type valve core structure, axial equilibrant
is little, allow to press difference, the stability is good.
The interchangeability of the collet is strong, disassembly and
assembly is convenient, easy maintenance.
Suitable many kinds of working occasions of core structure of
all-metal valve, reach IV grade and let out the standard, the ZXMO
type soft sealed structure valve core reaches VI grade and lets out
the standard, the ZXMQ type soft sealed structure valve core is
reached
Let out the standard to VI grade.
Valve body design according to hydromechanical principle section
low to flow group shed dish, adjustable range heavy , inherent and
adjustable than 50, specified flow coefficient increase 30%.
The executive body adopts the structure of many springs, highly
reduce 30% , weight to lighten by 30%.
Sealed regulating valve of corrugated pipe of the Model ZXPV, take
shape and totally seal to the valve stem moving, stop up the
hopeless fluid to leak .
The regulating valve of the Model ZXPJ keeps warm inserting set, it
causes the occasion stopped up to exchange the crystallization ,
solidify after being used the fluid and cooled. | | Part material |
