High Performance China Pressure Relief Device   .

Application:
A pressure relief valve (PRV) is a safety device that relieves overpressure in a vessel or system. When the pressure of vessel or system increased beyond the specified design pressure or maximum allowable working pressure, PRV will be opened automaticly to relief the overpressure for proteding the vessel or system. The PRV will be closed if the pressure reached specified design pressure so that to ensure the normal operation and protect the vessel or system.

Our Pressure Relief Valve has been designed and manuractured according to following Standard:

♦   ISO 4123-1 Safety Devices for Portection Against Excessve Pressure
♦   API STD 526 Flanged Steel Pressure Relief Valves
♦  API STD 527 Seat Tightness of Pressure Relief Valves

♦   ASME Boiler and Pressure Vessel Code Section VIII Division 1, Rules for Construction of Pressure Vessels

Peformance:
♦  Type: Conventional, Bellows

♦   Size:1" D 2"- 8" T 10"
♦   Class:150lb~2500lb
♦  Temperature:-268~+538°C

♦   Fluid: Gas, Steam, and Liquid
♦  Material: Carbon steel, Stainless steel, Alloy steel
♦   The allowable tolerance of the set pressure: ≤±3%
♦  Overpressure: ≤10%(gas)/≤20%(liquid)
♦   Blowdown: ≤10%(gas)/≤20%(liquid)

♦   Tightness: conforms to API STD 527

Features:

♦The solid nozzle is screwed into the body, which makes the maintenance easy.
♦  The shape of the disc holder has been designed to enhance the effect of the fluid thrust for an instant lift of the disc.
♦  Blowdown control is provided with adjustable nuzzle ring only.
♦  The adequate terials and clearance between disc holder and guide , spindle and adjusting screw assures disc to lift   successfully.

♦ The surface of both the disc and the nozzle seat are deposited with Stellite. Excellent flatness and surface finish of the seating surfaces by precision machining and lapping assure pressure relief valve to have high degree of seat tightness and long using life.

♦  The bellows of balanced bellows pressure relief valves can not only avoid and effect of variable back pressure in the system , but also protect spring and other trim components from corrosive media.

♦   Materials are chosen carefully , and the manufacture of the spring and the bellows has strict technological process. Each of them is tested and checked strictly.

Q:Question about bicuspid valve...?
Yes, some studies have found Bicuspid aortic valve to be hereditary. Some studies show that the incidence of bicuspid aortic valve can be as high as 5% in families affected with the valve issues. In the UK there is no routine screening for people with relatives who have BAV. If you develop any symptoms or problems then of course see your GP again.

Q:Mitral Valve Prolapse..Help please?
You can lead a normal health life with MVP. What it is is the valve between the left atria and left ventricle doesn't close fully like it is suppost to and some blood seeps back into the atria when the blood is being pushed out of your heart. MVP is more common then you think. The doc even said to you that your case isn't really severe. MVP cannot be cured without surgery at this time. However you'll be fine. Just keep to your doctor visits as scheduled to keep tabs on it.

Q:leaky valve cover gasket problem, ok or not?
Not to be mean but you can't work on what you can't see! Take the Jeep to a wand type car wash with a bag of quarters. Lift the hood and spend some time with high pressure soap and clean the entire engine and under-hood compartment. Don't bother covering anything. Leaking valve covers don't mean anything is wrong, it just makes a nasty mess. Remove valve cover/s and scrape old gasket material of the head/s and cover/s. The best valve covers in the world won't seal until the valve cover/s are completely flat. *This is an age old problem with stamped steel covers. If you want to get extra slick, chase down some aluminum cover/s. There stiffer and less apt to leak when you snug them back down. I'll let you in on a racers secret to make them seal. Buy a tube of Dow Corning or Permetex clear RTV silicone sealer. Scrape down the valve cover gasket surface till it's clean. Wipe the gasket surface down with CRC Brake Clean. Run a bead of the clear RTV on the valve cover and let it set-up for at least five minutes. Lay a Fel-Pro - Blue Stripe valve cover gasket on the valve cover. Seat it with your thumbs. Scrape-down the cylinder head where the gasket goes till it's perfectly clean. Clean the gasket seating surface on the cylinder head with C5RC Brake Clean. Lay a small bead of the RTV on the outside of the gasket which will meat the cylinder-head. Carefully set the cover on the head and gently alternately tighten them. It's OK to drive the vehicle as soon as you're done!
Q:boiler bleed valve replacement?
Very easy but quite slow. Open the bleed points on the upstairs radiators and the system will fill evenly. Shut the bleeds when the water reaches them of course. If the pump is accessible loosen the big screw head on the top of it and the will bleed air from the pump. When you think the system is full and the noise of entering water stops then go around to all of the upstairs radiators and check that there is no further trapped air.
