Product Description

3PCS Handwheel Forged Steel Trunnion Mounted Ball Valve

3 PCS forged steel ball valves represent the latest advances in ball valve technology for long-distance delivery pipes and general industrial pipelines. During the design process, it can withstand a variety of corrosive and non-corrosive media under harsh conditions, ensuring strength, safety, and tolerance.

Unlike traditional floating ball valves, when this fixed ball valve is running, the fluid pressure on the sphere is fully transmitted to the bearing, preventing the sphere from moving to the valve seat. Therefore, the valve seat will not bear excessive pressure. This reduces the torque on the fixed ball valve, avoids significant deformation of the seat, ensures stable sealing performance and long service life, especially suitable for high pressure and large diameter applications. Its unique spring-loaded seat assembly features self-tightening to ensure upstream sealing.

Frequently Asked Questions

Q1: What is the main advantage of a trunnion mounted ball valve over a floating type? A: In a trunnion mounted design, the ball is supported by bearings, meaning fluid pressure is transmitted to the valve body rather than the seat. This reduces operating torque and prevents seat deformation under high pressure.
Q2: What pressure ratings are available for this valve? A: This valve supports a wide range of pressure ratings, typically from ANSI Class 150 up to Class 2500 (1.6MPa to 42.0MPa).
Q3: Can these valves be used in corrosive environments? A: Yes, the 3-piece forged steel construction is designed to withstand both corrosive and non-corrosive media, with material options like Stainless Steel (A182-F304) available.
Q4: What are the available sizes for this product? A: Sizes range from 1/2" (DN15) up to large diameter 48" (DN1200) pipelines.
Q5: What operation modes are supported? A: The valve can be operated manually (via handwheel or lever), pneumatically, or electrically, depending on your system requirements.
Q6: What is the standard warranty period? A: We provide a standard warranty period of 12 months for these trunnion ball valves.
