Pneumatic Valve

Product Details:

• Valve body is designed to provide maximum stream line flow to minimize pressure drop as well as corrosive and erosive effects.
• Adequate wall thickness and sturdiness to avoid distortion caused by fluid pressure under operating conditions and also to withstand undue stresses on any working parts.
• Body is strong enough to withstand specified conditions of pressure and temperature.

• Bonnet is designed in the form of circular or rectangular sections as per the requirements of API 600 standard.
• The valve body and bonnet flanged joint is fastened by adequate number of studs and nuts.
• Bonnets are equipped with gasket which ensures a perfect sealing.
• Bonnets are designed to withstand same pressure as that of body.

• Stem is outside screw, rising type with trapezoidal threads for smoother operation.
• The stem collar is formed by forging from wrought material to ensure trouble free operation.
• Stem is machined to high finish, with accurately cut threads, minimizing packing friction and operating torque.
• Stem is provided with conical back seat surface to seat against bonnet back seat surface for re-packing of valve with the valve full open position.

• Bush is screwed on the bonnet.
• It has conical seating surface to meet corresponding seating surface of stem.

• Gate valves are provided with flexi gate wedge tapered on both sides, provided with deep groove inside lugs
• All the wedges are furnished with proper guides, reducing unnecessary wear on seating surfaces due to the movement of wedge.
• The seating surfaces of the wedge are precisely machined to achieve mirror finish.

• Body seat rings are screwed/welded to the body.
• The faces of rings are precisely machined to achieve mirror finish.

• Gasket is selected to match its suitability for handling particular fluid under specified conditions.

• Sturdy, specially designed for firm grip.

Product Details:
