Wenzhou Joepai Valve Co., Ltd. has been focusing on industrial valves for over 20 years and has a complete system for casting, machining, and testing. As the core of our safety and leak proof valve product line, the bellows series is exported to markets such as Germany, Italy, the United Arab Emirates, and Vietnam all year round. We are committed to providing customers with more durable and environmentally friendly industrial fluid control valves.
● Long cycle life bellows (2000 cycles) in Gr. 321 (stainless) or Inconel. Designed and successfully tested in high pressure/temperature conditions.
● Bellows monitoring port (optional): Connected to the space above the bellows to monitor performance.
● Non-rotating stem prevents torsion of bellows.
● Two secondary stem seals: (a) Backseat in open position; (b) Graphite packing.
● Forged for higher safety: Increased toughness, strength and fatigue resistance.
● Two-part bellows.
● Low torque due to: (a) Non-rotating stem prevents torsion of bellows; (b) Stem nut thrust bearings; (c) Central lubrication.
● Seating faces hardfaced with CoCr alloy, ground and lapped
