Product description
Single-seat plunger valve type hts-d pneumatic diaphragm single-seat regulating valve with well-designed processing, seamless connection and the long-necked type valve cover on the valve seat. And adopts the special processing methods, to ensure that the valve in the -45℃ ~-196℃ no drip liquid gas under the condition of leakage and internal leakage and safety requirements of harsh operating in normal condition.
The greatest feature of this product is in the -45℃ ~-196℃ under the condition of stuffing and the valve closed in the "double zero" excellent condition.
Type hts-d pneumatic diaphragm single-seat pneumatic diaphragm actuator and low temperature resistance of the single, two-seat valve consists of two parts: regulating valve. Thrust is generated by the gas chamber, the regulator to signal to the input pressure pneumatic membrane actuator, through the connecting rod drives the valve core, valve position changes to changes in the circulation area of valve, regulating the flow of media. It is different with normal temperature regulating valve adopts the long-necked type valve cover, that the filler is working at normal temperature. Applicable to -60 ~ -250℃ low temperature medium (such as liquid oxygen, liquid nitrogen) regulation.
