ANSI GLOBE VALVE
This API stop valve is a kind of gate valve. It has a valve disc in a hollow pipe. The valve disc must be rotated from one side to the other to open and close the fluid channel. When water enters the piping system, there are two valves: one for water supply and one for water return.
Product introduction:
ANSI stop valve is a one-way valve that can be closed in one direction. It is not connected to the water system, so it can be used on a ship or barge, or on shore. Stop valve is a kind of gate valve. It has a valve disc in a hollow pipe. The valve disc must be rotated from one side to the other to open and close the fluid channel. When water enters the piping system, there are two valves: one for water supply and one for water return.
Product features:
1. the stop valve is a compact miniature pressure relief valve used to detect leakage and control system pressure. Its compact design allows it to be installed anywhere in the system, and its compatibility with all fluids makes it an ideal solution for any situation. Add a stop valve to your pipe to control the flow of liquid from one side to the other. The stop valve can handle high flow and provide maximum flow in the smallest space. The ball in the center of the valve can rotate 360 degrees freely and can be completely closed when necessary.

Stop valve is a kind of gate valve. It has a valve disc in a hollow pipe. The valve disc must be rotated from one side to the other to open and close the fluid channel. When water enters the piping system, there are two valves: one for water supply and one for water return.
3. API stop valves are used in oil and gas pipelines, refineries and oil depots, petrochemical plants and power plants. These valves are designed to provide an absolutely tight seal to prevent damage to the system due to leakage or air leakage. The result of using modern materials and manufacturing technology is a durable valve that can be repaired cost effectively when necessary. Stop valve is a cheap and reliable valve type, which can control the flow of fluid and steam. There are many styles of globe valves, including gate valve, ball valve, butterfly valve, needle valve, gate valve and plug valve. The most common type is a ball valve design with threaded ends screwed together to form a seal. Ball valves are usually used in industrial and commercial applications with corrosive chemicals or high pressure.
4. flow control device, including gate valve assembly, gate valve housing and gate valve stem. The valve stem has an outer sealing surface in sliding contact with the inner surface of the gate valve housing when it is closed, and an inner sealing surface in sliding contact with the adjacent end of the gate valve when it is closed. API ball valves are used in the chemical and processing industries. In these industries, ball valves face severe loads, corrosive chemicals, high temperatures and / or coolant media. The ball valve is a non rotating control device that can be fully opened and closed. There is a flat hole behind the valve port surface of the ball valve, which can have a straight flow channel when it is completely closed. This may be an advantage in applications where complete closure is required to avoid leakage through the needle interface or other mechanisms.
Features and benefits
Unique non-rotating stemdesign is easily adaptable for actuation – with precision Acme threads and burnished finish. Valve suitable for horizontal installation.
Universal trim: 13Cr stem, 13Cr faced disc, and CoCr alloy faced seats – API Trim 8 suitable for service up to 850°F (454°C).
Seat faceCoCr alloy hardfaced, ground, and lapped to a mirror finish. Conical seat machined to fine surface finish.
Body guided disc accurately mates the hardfaced surface of the disc (hardfaced with 13Cr, CoCr alloy, SS 316, or Monel) with the surface of the body seat, which is ground and lapped to a mirror finish.The disc guides are hardfaced to extend the wear life of the disc guides.
Body and bonnet castingsare precision machined. One-piece bonnet for better alignment, fewer parts.
Stuffing boxmachined to fine surface finish.
Body and bonnet joint accurately machined to fine surface finish. Fully enclosed gasket.
Gland has two-piece construction for easy alignment.
Rotating stem nutin Austenitic ductile iron Gr. D-2C, renewable in-line.
Torque armreduces wear on packing rings and enables better sealing and reduces torque.
Impactor handwheels:Globe and stop check valves require higher closing torques than gate valves with the same seat diameter and pressure class. The most economical mechanism for tight shutoff is the impactor handwheel. Two lugs cast under the wheel strike simultaneous blows and give 3–10 times the closing force of standard handwheels. Impactor handwheels are supplied at manufacturer’s option unless specified by customer.
Flanges: ASME Classes: 150–300: 1⁄16” raised face.
ASME Classes: 600–1500: ¼” raised face.
Finish: 125–250 AARH for all valves.
