Quick Detail:
1. Two stem design: The upper stem has hardened threads, the lower stem has hardened smooth surface.
2. Upper stem thread lubricant is isolated from system media.
3. The lower stem performs vertical linear movement instead of screwing movement, significantly reducing the friction area.
4. The nonrotating lower stem eliminates galling between the seat and tip.
5. Stem back seating seals in the fully open position.
6. Double lock-pins enable steady and durable fastening of the handle.
7. Optional handle colors are available.
8. 100% factory test. Every valve is tested with nitrogen for leak-tight performance at its maximum working pressure.
Description:
stainless steel 2 valve instrument manifolds
Two Valve Manifolds are the most commonly used manifolds. They may be provided with test ports on the process sides and drain ports on the instrument side for drawing of the process and instrument lines respectively.
TF series instrument manifolds are used for static&hydraulic pressure based on the transmitter for pressure,
differential pressure,flow rate, liquid level and etc at home or abroad.3-valve &5-valve manifolds are designed for
differential pressure.there are many kinds of structure types and end connections for model selection.All the
instrument manifolds have been widely used in engineer projects of oil refining, chemical industry, electrics,
coal-to-hydroxide, metallurgy, nuclear power and so on.
Controlled by a group of needle valves made of stainless steel.The function of each valve(pressure-shutting off,pressure drainage or pressure balancing ) is determined by its definite position on the manifolds.All
these functions by its definite position on the manifolds.All these functions are undertaken by two kinds of needle
valves;needle valves with big bonnet are used for manifolds with nominal diameter of 0.156in(4.0mm),and needle
valves with small bonnet are used for the manifolds with nominal diameter of 0.125in(3.2mm).
Characteristics
1. Press up to 6000psig (414bar) for standard stainless steel body
2. Temperature for PTFE packing from -65°F to 450°F (-54°C to 232°C)
Temperature for Grafoil packing from -65°F to 1200°F (-54°C to 649°C)
3. Packing below stem thread isolates the thread lubricant from the media
4. Back seating design protects the packing in fully open position
5. Non-rotating stem tip
6. 100% factory tested
7. Orifice:0.157" (4.0mm),CV:0.35
Applications:
