Lifting ball seal pilot valve assembly, the pilot valve disc is made of anti-corrosion tool steel, which is ground by imported grinding machine to achieve 0.01% steam leakage.

Depending on the range, decompression springs of different colors and parameters are available for user selection.

Built-in 200 mesh filter to reduce impurity jamming and wear of pilot valve components.

The use of large-area pressure bearing main diaphragm, the use of copper plated material imported from Japan , can sense small changes in pressure while reducing all fatigue, compared with stainless steel diaphragm, the service life is significantly improved.

The main disc, the main valve seat is made of imported tool steel, through heat treatment + cryogenic treatment + aging to reach more than 60HRC hardness, with super wear resistance and cavitation resistance. The main disc adopts a spherical sealing structure for superior sealing performance, and the valve seat leakage class is ANSIIV.

The diaphragm or bimetal structure air exhaust kit can be replaced online.

When the steam equipment is turned on cold, the valve inner exhaust air valve device can be opened to increase the condensate discharge.DN15-25 can increase displacement by at least 50%-100%.

The high-strength stainless steel float adopts advanced welding technology,which is resistant to water shock and corrosion.

The spool seat is spherical sealed according to the pressure difference of steam, temperature, etc., can be paired with different sizes of spool seat size tomeet various working conditions.

The valve body channel is designed to avoid the direct impact of steam and water hammer on the float and improve the life.

Valve cover with three rows of water holes reserved design, open the valve cover rotating valve body, can change the flow direction on site.

The spool and seat are hardened for longer service life.

Equipped with water seal to reduce steam leakage

The valve is equipped with a filter screen to prevent dust and scale and protect the normal operation of the inverted door.

A small amount of non-condensable gas such as air can be discharged through the vent hole on the top of the barrel.

The lower open barrel type structure is more resistant to water hammer than the float type.

Either the bladder or the bimetallic structure emptying kit can be replaced online.

The 60-mesh double-layer filter screen blocks pipe impurities and can be cleaned and replaced.

Laser-welded precision float with stainless steel roundness of 0.01 mm.

S430 seat with vacuum heat treatment.

Three-drain design of valve seat reduces valve disc offset.

It adopts imported surface grinding machine for rough grinding, and the roughness of imported grinding fine grinding is less than 0.1Ra and the flatness is less than 2 microns.

SS304 material prevents the valve plate from jumping due to external temperature differences, reduces unnecessary steam loss, and also prolongs service life.

Built-in filter to prevent impurity jamming and seal wear.

The valve seat is made of Japanese SUS440 material, and after heat treatment, the hardness of the cryogenic sealing surface reaches 60HRC.

Original imported, stamped and formed, high temperature stability aging treatment. Ensures stable thermal thrust, resistance to superheat and water corrosion.

Six high-pressure bolts, made of B16, ensure a high-strength sealing of the middle flange.

Built-in stainless steel filter screen to prevent disc seat and bimetallic impurities from jamming

After heat treatment of martensitic stainless steel, 2 times of intensive research to ensure hardness and sealing.

The diaphragm of the membrane box is made of Hastelloy alloy, and the vacuum welding pressure chamber is adopted.

Stainless steel filter prevents seat jamming.

Spherical sealing disc with embedded G10 grade steel ball ensures highprecision sealing with roundness and roughness.
